This would make a great little lore item in some RPG to explain why there's a spell list.

'We have literal magic that can raise the dead and move us across the world in the blink of an eye. Why the fuck am I having to do dishes by hand?'

'Because no one actually knows how the spells we have work. We just have these spells left over from when they did, and 'clean dishes' isn't one of them.'

Removing Kier’s symbol changes the ethereal layout, which is pseudorandom. You can put anything with that symbolic signature in that spot and it would hold up the same.

Well, honestly, this one is written in Snek and i'm not really proficient with that.
