About Primordial shenanigans... I basically just took cues from the idea that Amul is there to offer occasional guidance and assistance. Putting Might into making a deal binding felt kind of weird and wasteful, since it isn't particularly miraculous, especially when I thought Jvan would wake up soon and my planned budget was much narrower.
It's also very much a Heartworm thing to do. Slippery little thing really isn't too keen on getting betrayed when you pack so little heat. Best to try and get the toughest lad in town involved and hope he cares. Phi, on the other hand, was happy to put her trust in a handshake, and even that she tried to wiggle out of.
Whether or not it actually is binding I have no idea. Heartworm seems to think so. That might be important later.
