Quasar

Deep within the Ruins underneath Silvarum, there's a portal filled with stars - a portal that can travel to other dimensions, other histories, other memories. It's a powerful place, in the middle of a dangerous maze, but it has a protector. To ensure that no meddlers break into the portal and cause horrible harm to time, Quasar has guarded it for as long as they can remember.

They suppose they're an angel of sorts, sent by the creator of this planet to defend a single location. But they still dream of seeing the stars out there, and often they'll dive into the portal and visit far off planets.
