Ostoja

Ostoja is a set of two small islands in the Commons. They are located inside a magical thunderhead storm of immense size, seemingly protecting them. The reasons for this protection have eluded scholars: Ostoja is quiet, self-sufficent, and lacks anything of immediate interest.

History
Ostoja was discovered after the Cascade. It is thought that it could not have existed as it did prior to the Cascade, since the storm seems to protect the islands within quite specifically. Ostoja inhabitants show little knowledge of the history of the thunderhead, however.

Due to the difficulty of accessing Ostoja, the number of diagnostic tests performed in the thunderhead have been low.
