The Velyn Harbor Mages Guild
The Velyn Harbor Mages Guild is a guildhall in the central part of Velyn Harbor housing a local branch of the Mages Guild. It is a two-story building with upstairs and downstairs areas. The ground floor houses all the resident vendors of the magical supplies along with alchemy and enchanting stalls. All the inhabitants can be found on this floor, either tending their stalls or practicing spell casting. There is an alchemy station, a dye station and two enchanting tables, all available for crafting. A note, Dead Man's Drop, which adds a map marker to the mine with the same name, can be found here. An extensive library is situated upstairs, with quite a few bookshelves along the walls.
When you first arrive in Velyn Harbor, the building is accessible but overrun by Drublog invaders. The Mages Guild services become available only after the successful completion of the One Fell Swoop quest during which you need to liberate Velyn Harbor from two invader groups attacking the city at the same time.
