Serpentis Major

The Serpent Star, or Serpentis Major, is a mysterious extraplanar entity. The reside within their own little corner of the Astral Plane, surrounded by voidsnakes. These same voidsnakes make up the physical form and consciousness of Serpentis Major. The snakes surround a green ball of fire, but it is unknown if the fire is a part of Serpentis Major, or entirely separate.

The exact extent of the Serpent Star's powers are not completely understood, but they have been shown to be able to grant sapience to monsters, and spontaneously generate physical objects.

They consist on a yellow-green liquid known as Monster Energy. If not given enough, the Serpent Star is unable to use its power to their full extent.

The voidsnakes of the Serpent Star seem to have their own names and identities, but are part of an intelligent hivemind.
