Koskun Keep. Art by Pat Morrissey.
Koskun Keep was a stronghold in the
Koskun Mountains on
Ulgrotha which was home to
goblins and thieves. It was ruled by
Eron the Relentless, who had an agreement with
Aysen to buy food from them in return for not attacking their towns. The goblin
wizards from the Keep have begun egotistical duels against mages from the
Wizards' School that may threaten to hinder relations between the two powers. At the base of the keep is the fortress of
Strongrock.
