But generally speaking, unless you're sitting around in the Vale of Infinite Horror, carrying horror-marking equipment, facing astral mages who use Horror Mark or Astral Geyser, get hit by a horror sent by somebody else (horrors tend to have Astral Hooks which horror-mark you; also, non-blood forging or rituals during Astral Corruption), or cast spells which horror-mark the caster (Hell Power comes to mind)... they're not spontaneous.

Don't sit in the Vale wielding Magebane, a Robe of the Archmage, the Boots of the Planes, the Forbidden Light and the Gift of Kurgi unless you enjoy making very otherworldly and violent acquaintances.

What are all these items and places? Can I read the game content in some library, Dominionapedia?
