Blister

The Blister was a volcano on the Pitharan Mainland. It was the second-largest volcano in Echelon. Considered dormant for most of its existence after the end of the Dawn War, the Blister was nonetheless a focal point of magical energy along the Leomund ley line, and contained a permanent portal to the Elemental Plane of Fire. The portal was guarded by the Stigmata Garrison from 1342 LA until 2358 LA.

The Blister suddenly erupted in 2358 LA during the Meloran Crisis, destroying the Garrison there and wreaking havoc on the nearby city of Trigonon.
