Great Fissure

The Great Fissure is a colossal rift in the land, running northeast to southwest and striking all of Alassia into two. The depths of the rift are unknown, and are left unexplored by surface dwellers, because the walls of the fissure quickly become the undisputed domain of the kingdoms of the underdark. The fissure is one of the few places where the underdark and the surface are in unregulated contact. Still, several important Alassian sites exist along the fissure: several of the greatest votive crypts and many major Mazurist pilgrimage sites, including the Holy City itself. It is spanned by a handful of ancient bridges, each dozens of miles long and made of monolithic stone.
