Roy stares, gaped mouth, at some of the artifacts on display. A pair of his gloves are hung up, the throwing knives of the late Maes Hughes are stacked on a shelf, and most terrifying of all, a single red orb, glowing brilliantly in the sunlight.
"H-How? How do you have these? Maes's knives and...and a Philosopher's Stone? Who are you?"
"I RECOGNIZE SOME OF THESE THINGS TOO! THIS BLUE ORB, MY FRIEND UNDYNE FOUND IT WHILE SHE WAS DIVING IN THE TRASH DUMP, AND I'LL BE DARNED IF THIS TRIDENT DIDN'T BELONG TO KING ASGORE HIMSELF!"
"COME TO THINK OF IT, I THINK I SAW A FEW MONSTERS OUTSIDE..."
Papyrus is considering something...
Old Man: "...
I suppose you need to know.
I am Lun Colordeep.
One of the first to enter this... world.
Let me tell you my story.
I was a lone wizard, helping a mighty dwarven civilization, The Bastion of Dawn.
However, during a magical experiment during the Elven Wars that occured, it backfired as elves invaded and interrupted the ritual and sent me here.
I later gained the ability to see into other dimensions and to travel there as well through my studies.
As for what this world is, it is a composite dimension.
A mixture of worlds all rolled into one.
However, they aren't YOUR worlds, per say.
Just parts of very similar universes.
Those artifacts, I collected for study.
Mainly the Philosopher's Stone.
Alchemy's a strange subject.
And that blue orb, Papyrus?
Really a worthless little thing. Not much power."
