The fourth layer of Acheron is lightless but filled with fastflying, razor-thin shards. Some shards are little more than needles, while others are miles wide. The largest shards have their own objective gravity like the cubes of the upper layers, as well as a breathable if icy cold atmosphere. The constant blizzard of bladelike shards makes acanthus inimical to creatures and objects alike. The shards are black ice, frozen into thin layers. Their collisions break them into progressively smaller shards, and eventually into needles and then dust. The shards all originate from a single source: the night-black boundary of acanthus, a sheet of infinite, magically charged black ice. No one knows whether the ice sheet is a boundary or a barrier between acanthus and some deeper, more sinister layer. Some say that the ice is the source or destination of the River Styx, and that every memory stolen by the river still exists, frozen into the black ice. Whatever the truth,, the ice sheet has objective directional gravity, and it is possible that it is simply a shard of black ice so large that it is mistaken for acanthus’s boundary.
Surviving an Ocanthus Bladestorm
Creatures that are not projected by some supremely strong artificial structure (which eventually is breached anyway) are constantly vulnerable to shards slicing through the darkness like knives. Creatures and objects are subject to the equivalent of a greatsword attack (2d6 points of damage) every round at a +10 bonus on the attack roll. Damage reduction does not apply, but hardness does.
