OCANTHUS

The lowest layer of Acheron is the most openly hostile. Its gray sky is filled with shards of black razors, some large enough to walk on, while most are small enough to rend flesh from bone. The razors are sharp, and if there were any cubes on Ocanthus like the other layers it is likely they were destroyed long ago in one of the fierce razorstorms.

The strange thing about Ocanthus is that the shards are not iron or metal, but instead black ice. It is rumored that the bottom of Ocanthus, and thus Acheron, is actually an immense sheet of ice, and this forms the source of the razor shards that fill the layer. Some planar scholars refer to this mysterious site as the Sea of Memories as they believe it is either the source or destination for the River Styx, and that every memory stolen by the river is kept frozen there.

The theory has lured desperate travelers who have had their memories robbed by the River Styx to go in search of it, but to date no one has found it. Ocanthus has one native species, the bladelings, and in their strange walled city of Zoronar they do not offer answers to any travelers.
