Goddess of the universe. She can make new planets, stars, and asteroids (out of anger). For the most part she's a good goddess with good intentions. But if you cross her she will retaliate. She has a sneaky side. When she retaliate its when you least expect it.
Hemi-Mortallia is a demi god. She has the power of death and the underworld. Hades is her father. Her mother was immortal & who died after having her (since she's death). She has a very dull personality but is creative. She cannot directly kill anyone but she can cause deaths and bring people back from death.
Treesta is the Monster of the woods/trees. She controls all plants in every way possible. She is evil and scares anyone who dares to enter to woods. She was only a normal tree when she was accidentally cursed upon by Hecate, who assisted Demeter. She was reciting a spell in the woods and the power went to tree. It was not brought to Hecate's attention. She's basically turned a tree into an immortal monster.
