Basically in this universe, instead of simply being put there by mages thousand of years ago and staying mostly intact, the Barrier imprisoning the monsters has to be maintained by each generation. The problem with this is that humanity's magic slowly dwindles to nothing, so now, they have no choice but to create mages to send up there instead. But how do they keep it intact? and how did they create them? When one of them falls through, they learn the truth...
Yet another UT AU. Yaaay. Is it a "Frisk" or a "Chara"? It's both.
