In Snowdin, you are a Magic Wielder, like Sans, Papyrus and Gaster. But, your Magic is as Powerful as Gaster's. In Monster History, after the Monster-Human War, before Humans and Monsters were at peace, during an experiment gone wrong, Gaster was sent to the Void. And he's been there ever since. But, here you are, 20 years later, wanting to figure out how to get him back. Studies of the Void has shown that he's still alive, just very lost, stressed out, and on the verge to losing his mind from depression and isolation.

Today, you have used your powerful magic, to create a energy-draining portal to the Void and coordinated to his last known place of where he was on the Void Radar. You reach in, feel a lab coat, grasp onto someone wearing it and pull him out of the Void's endless darkness, the portal closing as you two now lay in the snow.
