Ursa is doom.
Ursa is rage. She is the very force of destruction. Ursa has escaped the realms of the Divines and has entered the land of the living in her solid form.
Ursa in her solid form is told to be a giant tall shadow bear monster. She is black with a black shadow fog aura and shining red eyes.
She is located on the isolated island of Yellowrod, where she sleeps in hibernation in the Goblin's mine.
Only the royals know about her, and the Goblins, but they are too afraid to even speak her name.
The Goblin Shaman's Dark Magic is the only thing that keeps her asleep.
Ursa's presence in the land of the living has given the Humans an unique power. They have found out that the closest creation to Ursa is the bear, and with a blood sacrifice to Ursa she will give you the power to soulbound with a bear. That combination will make you as strong as a Wolf and give you the destructive power of Red Magic.
But there are no bears at Yellowrod so that is trouble elsewhere in the world of Crea. (Phew).
The Humans that worship Ursa are called Ursanias.
The Red magic that comes with their soul-bounding makes them immune to pain and they only seek selfish destruction and domains of everything. Not even Goblins get that mad, they just seek some fun in the random chaos they create. But Ursanias... It is only selfish madness.
