Sulphire Crystal

First discovered by the party in the aftermath of Session 1: The Bristlebeard Brewery, a Sulphire Crystal appears to contain the soul essence of whatever beings find themselves trapped inside of it-- for example, Ian Taggart's bird. Acting as an arcane conduit, the crystal has been shown to possess terrifying power. In the hands of Gnolean Vext, a Sulphire was used in conjunction with a strange ritual amulet of The Wyrm Cult to create a tear in The Weave large enough for the necromancer to access the primordial realm of The Aether.
