Skyrim:Letter from Falk Firebeard
<Alias=Player>,
Over the last few days we've had some disturbing information come to light regarding the events at Wolfskull Cave and the summoning and binding ritual you interrupted there.
Given your involvement with that event I'm asking you to return to Solitude to help us once more. I'm wary of putting all the details in print, please come see me at the Blue Palace.
Sincerely,
