"This is a unique and perhaps under-appreciated thing, quite unlike any other OSR product, that deserves more attention." Patrick Stuart - False Machine

"There's a feeling that this a world on the edge and you've just walked through the door while university is almost in full panic mode. If your expecting Harry Potter's universe, absolutely forget it! This is the world that would have burned Harry's corpse, created a display for the ashes, then put them in some back corner to be used for a demon summoning later" -  Eric Fabiaschi - Swords & Stitchery
