This is my version of the Fixed Logrus. The style of presentation is meant to be similar to that used in the rulebook. There are no Attribute requirements.
Psyche is useful for finding the stable part, and Endurance is useful in surviving it.
Sorcery may help one find the stable part. A character with Human level attributes may attempt to traverse it. One becomes an Initiate of the Fixed Logrus by waiting for the unchanging part to appear on the surface and leaping upon it. Miss it, and the Fixed Logrus eats you alive, spitting out a chaos creature of its own creation, or perhaps merely a mangled corpse, or nothing at all. Often, even if one can find the stable part, the Fixed Logrus kills you.
