How far does axefell Sans have to travel too hunt? And how did he preserve Papyruses spine from dusting?

He has to travel pretty far, well into Waterfall, once his captured quarry expires and he can no longer harvest anything more from them.

As for the other… Well. At one point, we were kinda holding on to that information, but we’re not really planning on doing anything for Axefell, so. Here we are~

Sans’ basement in Axefell bears witness to a crime even worse than eating his own kind. He has been harvesting their souls, and holding them captive in soul jars of his own creation, in an attempt to replicate the power of a single human soul for himself… so he can escape. Without their souls shattering, their bodies remain in stasis, thus the rotting corpses in the woods, the severed heads… His brother’s preserved spine and skull.
