- Talk to Mirili Ulven about her research.
- Collect the ingredients and return them to her.
- Talk to Mirili Ulven about her bestiary.
- Bring her each of the animals.
Starting the Quest
In Highcross, you will get a topic pop up saying "Mirili's Research". Asking around and mentioning this will only receive comments on how obsessed she is with plants and animals, so you will have to ask Mirili Ulven herself. She can be found at her house after dark, but before then she will be outside collecting samples around the Settlement.
When you have found Mirili, she will be very secretive about her research, assuming you wish to ruin it. After further persuading (getting her disposition up to 60) she will be surprised that you actually want to help her. She gives you a list of various rare items to collect and says she will pay you 10 gold coins for each sample. Despite this, she will only pay for one sample of each item.
Finding the Ingredients
Note that Mirili Ulven will accept stolen samples of any ingredient, and she will accept ingredients that were collected before the quest started. Simply collecting ingredients as you explore Shivering Isles and do other quests will usually be enough to get most or all of the ingredients, possibly allowing you to complete this portion of the quest within seconds of starting it. However, two ingredients are dropped from creatures (Scalon and Shambles) which do not appear randomly until you are at least level 7. If you are of a lower level than that, Xaselm is the easiest place to find both Scalon Fins (as well as one guaranteed Scalon) and Shambles Marrow.
Each ingredient's article provides full details on where that ingredient can be found; only plants particularly close to Highcross are mentioned here. It may be useful to print or save a copy of the ingredient list to use as a checklist of the ingredients you've delivered.
- Alocasia Fruit - Harvested from an Alocasia plant; a few can be found right outside her front door, to the left of her house.
- Aster Bloom Core - Harvested from Aster Bloom plants. One is growing in the archway of Bruscus Dannus' house.
- Black Tar - Harvested from Dementia-variety Mushroom Tree Saplings and Black Tar plants.
- Blister Pod Cap - Harvested from Blister Pod plants, which are only found in Dementia.
- Congealed Putrescence - Harvested from Putrid Gigantea plants, which are only found in Dementia.

The Next (and Final) Step
(This can be done before completing the Item List)
After finding and giving a few of the wanted ingredients to Mirili, she will remind you to ask her about her bestiary. She explains that she wants to start collecting animals and that she wants you to lure the animals to her. If you are at least apprentice level in Illusion skill, she offers to sell you Command Creature spells with which you can calm and lure the animals back to her, depending on their levels. Depending upon skill level, she will offer the spells Mirili's Apprentice Command, Mirili's Journeyman Command, and Mirili's Expert Command.
Each of the four creatures requires you to have found a certain number of ingredients before Mirili will speak with you about that creature. You will receive a leveled gold reward once each creature is brought to her:
- Baliwog (must have found 6 ingredients) - Mirili first requests that you bring back a Baliwog, a giant lizard-like creature. Any type of Baliwog will do. Baliwogs can be found along most shorelines, and occasionally on the road.
- Elytra (must have found 12 ingredients) - The second beast that Mirili wants you to bring is an Elytra. Places where Elytra can be found are detailed on the Elytra Ichor article. Elytra Nobles are the most powerful version of the creature that you can capture with the expert spell she gives you.
- Gnarl (must have found 18 ingredients) - The third beast to collect is a Gnarl. Places where Gnarls can be found are detailed on the Gnarl Bark article. The spell Mirili gives you won't affect an Elder Gnarl, but will be sufficient for lesser versions of the creature.
- Scalon (must have found 24 ingredients) - Places where Scalons can be found are detailed on the Scalon Fin article. Scalons cannot be found outdoors until level 9, so this stage of the quest cannot be completed by lower level characters. Mirili will allude to this by informing lower-level characters that they're not yet powerful enough, though the quest will proceed normally otherwise.
Tactics that can be used for any of the creatures include:
- You can use Mirili's command spell to compel a creature to follow you back to Highcross; you can also use your own command spell. Custom spells with magnitude 100 can be particularly helpful for dealing with high-level creatures. Keep in mind that her spells are cheaper in Magicka cost than normal.
- Alternatively, you can find a creature and just let the creature chase you back to Highcross. It is best to use this tactic early in the morning when the residents of Highcross are inside: any residents will attack your creature.
- Similarly, if you're bringing them in along the Overlook Road, watch out for Golden Saint patrols as they'll likely kill your creature.
- Be advised that Scalons have a very slow walking speed; it may be more efficient to let them chase you (they can cover more distance with their jump attacks) instead of commanding them.
Once in Highcross, getting Mirili to subdue the creature without killing it can also be a challenge. Sometimes, even in close proximity, Mirili won't turn hostile towards the creature. Tactics to get her to subdue it include:
- You can lead (or be chased by) the creature straight into one of the holding pens in the center of town, then close the gate behind you. Finding Mirili before the creature is in a holding pen is generally not recommended, since Mirili will not try to tame the beast until your command spell has worn off, at which point she is likely to kill the beast.
- If you can't get the above tip to work, then while Mirili is outside the town, attack the creature three times with your weakest spell/attack while it's still under your control. This will encourage Mirili to join the fight. At that point, cast protect or heal spells on the creature until Mirili can subdue it.
- Occasionally it may be possible for you to get one of the creatures you have under your command to follow you inside Mirili's house which allows you to let her capture it in a controlled environment where the other villagers will not interfere, lessening the chance of the creature's death. This, however, cannot always be done.
- The creature found afterwards in Mirili's Bestiary always has the same appearance, independent from the variant you captured. For example, a captured Elytra will be replaced by the same "Mirili's Elytra", whether it was an Elytra Matron or an Elytra Hatchling.
- Something you can do to help your creature survive the encounter with Mirili is to cast spells on it such as "Protect Other" and "Remedy Friend" during the fight. Doing this should allow the creature to last longer, thus giving Mirili more time to subdue it.
- Mirili's Command Spells cannot be bought after completing the bestiary part of this quest. These are cost effective spells, so you may want to wait on completing that part.
- The other residents of Highcross may attack your creatures on sight, even if the creatures are under control of a command spell. To avoid this, you may wish to take a roundabout route and enter the town from the south, or choose to only enter town at times when the other residents are not around.
- This bug is fixed by the Unofficial Shivering Isles Patch.
- After Mirili takes the Baliwog, she may be stuck in the house, and won't subdue the Elytra, which promptly kills everyone else in town. Casting a frenzy spell on her gets her out (popping her one in the face works, too), but then she's stuck again when the next beast is brought. You can try to avoid Mirili getting stuck in the house, but it requires quickness and a bit of luck, so save before trying. Once a creature is tamed, follow Mirili into her house, and speak to her. She will reward you. Then exit the conversation and immediately head out of the house through the door. If you can get out of the house before Mirili does her greeting that forces you back into a conversation with her, she should follow you out in about an hour, and not get stuck. Outside, you can speak to her again normally about the next creature she wants you to capture.
- This bug is fixed by the Unofficial Shivering Isles Patch.
- After bringing all the ingredients, Mirili's dialogue reverts back to the initial "Want to help. Here's a list." Her dialogue does not change to reflect the fact that you have collected all the ingredients until the bestiary portion of the quest is also completed.
- This bug is fixed by the Unofficial Shivering Isles Patch.
- After you have given her all the ingredients, Mirili will begin to follow you from a distance. An example is leaving through the portal to Cyrodiil and returning later to find her right at the beginning where Haskill first was introduced, only to say she is busy and walk off. She may even follow you to Cyrodiil and then stay there. She stands by the portal, but doesn't come back through. You can talk to her, but she doesn't go back through. If you sleep in a bed anywhere within SI except Duke/Duchess' private quarters; your sleep gets interrupted by her intrusion into your bed. She doesn't seem to follow you to places she cannot reach; (e.g. A bed in Dire Warren) so the risk of her getting stuck within SI is minimal but be sure to save before leaving SI.
- If you give Mirili multiple ingredients at once, she may not pay you for some of them.
- During the quest, Mirili will sometimes go through the portal to Cyrodiil and stay at the door in the Heartlands next to S'fara and Gaius Prentus. The only known workaround at this point is to load a previous savegame as she will never go back through the portal, even when attacked. You can attempt to spawn the remaining creatures via console commands, but she will always attack them and won't subdue them like she is supposed to.

- Not all Journal Entries may appear in your journal; which entries appear and which entries do not depends on the manner in which the quest is done.
- Stages are not always in order of progress. This is usually the case with quests that have multiple possible outcomes or quests where certain tasks may be done in random order.
- If an entry is marked as "Finishes Quest" it means the quest disappears from the Active Quest list, but you may still receive new entries for that quest.
- It is possible to use the console to advance through the quest by entering
setstage SE37 stage, where
stageis the number of the stage you wish to complete. It is not possible to un-complete (i.e. go back) quest stages. See SetStage for more information.
