i wonder what an all hope player session wouod be like... or a session with more then one time player, dose that mean theres 2 reboot constructs? and other rare accurences like that in diffrent sessions like secret bosses or randomly powerfull artifacts spawnned into a session by chance

Well, an All Hope Player Session could be like any other Session depending on what each relates their Hope to and what their Class is, so who knows. Two Time Players, however, it seems that there’s only one Scratch Construct, and sometimes not even a Scratch Construct- Aradia doesn’t have one, implying there’s not just ‘one per Time Player’, but one per Universe.

As for Secret Bosses or Secret Loot, with Yaldabaoth giving Jujus as Loots it definitely makes it possible there could be weird secret Loot in some Lands. As for ‘Secret Bosses’, well the Lich Queen seemed like a one-time boss kind of deal during Cascade, right?
