I have went to another dimension or world before this one. Before coming here, me and Pooka had arrived in the world known as the Realm of Stories. In there, people pulled into there are given Essences of characters from myths, fairy tales and legends and we often helped in restoring the world by reenacting stories and running errands.

Bark!

In fact I was fighting a big entity who was trying to destroy the world when it tried to escape and inadvertently took me, Pooka, and several others into this world.
