Doggo

Long ago, humans and monsters lived together on land. One day, they broke into a war, with the humans winning. As a result, humans sealed monsters into Mt. Edmond, which monsters now call the Underground. You, a human, have fallen into the Underground, and you somehow made it past the Ruins into the actual Underground. You pass by Doggo's sentry station, and he doesn't seem to be friendly. Huh? Who was moving? If something was moving...I'll make sure they never move again!
