Sans from the phoenixtale au was ruler of the underground till a event happened which shattered the timeline, Sans is one of a few that survived the event and he lives with Lumina and Papyrus in a special space in between the timelines. In this AU sans rarely is seen in his phoenix form only when fully angered will this form appear. The Phoenixtale AU will be festured on my channel TwinklePhoenix on youtube and ill upload more of my work here.
