KOTL Storyline

We just made VRBA canon and Nubby's KOTL must be canon.
Why is Nubby’s canon again?

Because he has a major character from every KOTL making an appearance, and it's quite a big KOTL, so it's almost 100% canon.

Ok then.
The existence of King Ryan and various characters from his games in my universe guarantees Kind of the Ladder’s canonicity.

Each KOTL in the canon should be their own universe (except VRBA, it's an extension of one of the KOTL universes)

Ok. Since headsets originate from your universe both canonically and in a meta fashion, it’s safe to assume it’s an extension of yours.
Everything's a universe if you look hard enough.
I’m looking at the fingernail I bit off. Maybe I’m not looking at it correctly.
