Map of the surrounding areas

Walking next to the river Acheron, a beaten path can be spotted that leads to the entrance of a cave with the inscription "O∏OIO∑ M∏AINEI E∆Ω NA ∏APATA KAΘE E∆∏I∆A" engraved on the stone on top of it. Around, there are many creatures, each one wearing a color-coded necklace that indicates they live in the Menagerie set on that place. Most don't attack visitors, and all are trained to protect the other members and to never go too far away from the cave and the surrounding areas.
