It has been a rare case to have seen one of these creatures coming and going from the reality they stand upon.
Only from references of a bumbling ex-aspirant have people pieced together how they do such thing.

Usually such observations are too late, with only a pool or a smear of ink left on a surface and a perplexed individual having missed the event. But the one cognisant person to have returned seems to recall these creatures jumping at a surface, seeming to splatter against it.

With ink smearing the wall as its volume is dragged... or drained... to somewhere else. When this aspirant was invited, they were told to follow through: A viscous ripple carried them through the solid wall as they entered, a relatively short trip for them, soon emerging in that realm of ink and false-light.

Yet there it was, that creature reforming once more to whole, like the staining mess that brought them here was no longer what composed them.
With a wet gulp the passage closed behind them. the hole that previously granted them entry vanished from the air, like a wound healed, like it was never there.

Such technique objects to the lawful boundaries of realities. But its utility is not without merit. For such plane-walkers or aspirants, these lagomorphs are a useful bunch to tag along with.
