I can't figure out how the treasure worked. Caliborn has it and the kids go fight him, then the B1 kids get trapped in there forever, but when do they go to fight him? And somehow while they're trapped in there it becomes intangible and John can reach in and change stuff? But he's still theoretically trapped in it? Vriska also uses it to fight LE so do the B1 kids get released and defeat him? The wiki says when caliborn sends a snap they go fight him but that doesn't make sense to me.
They credits were leading up to them going to fight Caliborn. The treasure can only be activated twice under very specific circumstances. The first time being to help Caliborn (him sealing the B1 kids in it) and the second time against him (when Vriska uses it). After Caliborn used it he sent it to the Furthest Ring where time is all weird. When John went to interact with it the circumstances of its use where not appropriate which is why he couldn’t actually touch it. And it is Unknown if the Beta kids got released from it upon it’s use against Lord English.
