"What would be the point" is a good question. And I know from experience that slipping through worlds is energy-intensive - and we cheated back home. Maybe being an Anchor will be relevant after all.

...further speculation at this point would be baseless, don't you think? But it's something to keep in mind.

That said, it might be wise to start looking for... a way out. Of the area with these sparks, if not this world.
