Pocket Dimension island
Few are brave enough to explore the dark nooks and crannies of the pocket dimension... but if you are, there you'll find the majestic Magical Sanctum. Standing in the center of a grove of alien trees stretching into the sky is a mysterious Titan whose name was originally lost to history, but which was later revealed to be Enchantler. It aspired to transcend and become a Colossal, but when it proved impossible, it fled and found a way to the pocket dimension. There, atop its pate and formidable antlers coursing with Monstromantic energies, Enchantler founded a sacred place for Magical Monsters to truly feel at home and perform a solemn hymnody to a place all their own in the Monster World.
