Riverside Training Ground

The Pack of the Ashes features an interesting educational system, in which Learners train in small packs under a single Teacher. They all stay in a well-protected area-- which is this strip of perfect (albeit barren) land, with a steep slope next to it and a wide river on the other side. It's hidden well from enemies and provides learning material for each ranking. However, it sacrifices its safety from floods and escape routes for enclosure.
