This is the Gathering ground of Cerno, for new mares to come find a home or for anyone to come to get away from their land. This land is also somewhere that they can gather. Cerno is the new half of the island that was once uninhabited by the others of Broken Wings, but Cerno doesn't know that those in Ibidem exist either. The common can be a dangerous place as it is closest to the Pit, where horses can easily fall and perish in.
