While we're on the topic of companions, is Hatemace an AI or is he just like...Hatemonger's secret third globule hidden inside a mace? It sounds like AI work on Warhammer/Dune rules, where they became too strong and had to be genocided. It runs on batteries power cells, but it's clearly capable of at least some sentient thought, even if it's basically just Hatemonger but smaller. It would be very on-brand for the Beholders to use their fallen or ancient brethren as weapons, so maybe Hatemace is like a weaponized Servo-Skull?
