Grmlch
AKA Gargalack.
A shadow demon whose name is bizarrely difficult to remember how to pronounce--he possessed Diogenes during the Danger Gang's (ideally last) ill-fated sojourn through the plane of shadows. His aims, at the time, were merely to leave the plane of shadows to find a place that was less boring. While in the prime material plain he quickly discovered that he wanted to become a god and, for a time, thought befriending the Danger Gang would be the best way to accomplish this end. He aided them throughout their entire quest for Harivarma (through under water palaces, the north pole, and Ool). During the final fight with Harivarma he decided, against his better judgement to try and help out while he had only a few HP. This went well enough for him, until Utpala cracked his stick in half, blowing him back to the plane of shadows. DG questnotes for June 6th (and perhaps a few days prior) are written from his perspective.
He appears to respect contracts.
He is aware of 'the great struggle' and his alignment vis-a-vis this is unknown.
