(I'm still working on this, so the design and lore are subject to change.) My Horrorhorror take :3 Lore: This isn't a continuation of Horrortale. Like Horrortale, this takes place after the Exiled Queen ending in Undertale's neutral route. However, Wild Lands takes place after the version of Exiled Queen where you've k1ill3d Undyne and 10 normal monsters. The underground descends into complete anarchy due to there being no government and- just like in base Horrortale -the famine caused by the core malfunctioning. Sans was at Grillby's when the core malfunctioned and Grillby himself went out badly, getting caught off guard and getting burnt as Grillby was thrashing around. He teleported back to the ruins after putting out the fire, but he was in critical condition. His clothes were badly burned, his stats were halved, and now he is unable to summon gaster blasters. His new clothes were made by both Papyrus and Toriel.
