Overall really impressed with this Chapter.
One concern I had with the use of GLTR for the Wearable Crest GBM Auctions.
A competing guild or whale could act maliciously and push up the price in the auction for a wearable crest resulting in the crest being owned by the whale/competing guild and sitting idle (or they could resell it to the guild at inflated prices) rather than with a guild that has focused on acquiring those wearables.
Edit Proposed improvement:
What if instead of glitter wars for getting wearable crests it is a dao vote? If you or your gotchi owns that wearable you get 1 vote per unit owned. Then the vote can be delegated to a guild. Votes are tallied up and the winning guild gets the crest. If you want to support GLTR tokenomics there can be a fixed GLTR fee (set by Aavegotchi DAO) to claim the wearable crest post vote.
Proposal: Replace Wearable Crest GBM Auctions with DAO Vote with Fixed GLTR Fee
