@rng_malrab thanks for your long reply!

Caliborn and Calliope were born naturally, so I think ectobiological player creation is more of a trend than a mandate. The cherubs do have their own temporal fuckiness, but the fact that Omega kids in HS2 will also be players suggests that natural born people being able to play the game is intended to be possible!

Since tiers are supposed to be the "levels" of SBURB, I've always thought the Kiddy Campersash was the set of achievements, just like you! If I remember right, Caliborn already had some on his when we are shown the sash, so maybe you can get achievements before you God tier too? I think it would be really cool if SBURB had achievements, preferably loads of them. It would be interesting. We know each tier gives boondollars (and possibly more?) as a reward and that reaching the tiers requires some form of (solely combat or not?) prowess to be shown by the player.

IIRC, underlings are created by Derse and given to the command of the Denizens; and they are given the grist that they hold. Does this mean grist is created somehow, or is it given from a hoard? I don't know! But underlings likely are designed to carry grist, as it's a (mostly) non physical resource. The denizen has their hoard, but I don't think we're given an inclination to think they drop grist themselves. To add to that, I think it's been hinted that lands do have exclusive grist, though I usually tend to think that there is a finite (unless you alchemise more) list of grist, some of which are exclusive for specific types of land.

Creating dream bubbles would be hard work that requires you to both be aware that horrorterrors are capable of creating such constructs, have an ability to commune with them and also give them reasons to create the bubbles, but if these things are true I don't see why not!​
