From publisher blurb:
In this series, Kenneth Hite looks at the creatures, species, and monsters of the Cthulhu Mythos from every non-Euclidean angle. Alternate versions and new explanations provide the same jolt of mythic bisociation that the gods and titans receive in the TRAIL OF CTHULHU corebook. Hite traces these foul things through their legendary history, and provides further clues for any Investigator to follow. Horrific scenario seeds burst and bloom, story spines protrude and deform, in a blasphemous garden any Keeper can harvest.
“You make the usual mistake — of thinking of them as being like ourselves. They weren’t.” God or monster? Species or phenomenon? Dragon or disc — or discontinuity? Invisible, invulnerable, inexplicable — the vile vortices of the lloigor encompass all and care for nought.
