T'Soarima - also known as the Red God, The Bloodbringer and the Rusting Queen - is a god mentioned in Viktor Welsh's 'Lost Gods' book.
She presents as a gigantic dwarven woman, wrapped in bear furs and is often coated in fresh blood. The metal in the armour, crown and mace she wields is often rusting as she spurns the trinkets and luxuries that detract from her purpose.
She is associated with warfare, tactics, glory in battle, hunting, smithing, mining and triumph. She is the eldest sister of the Elder Gods. It is said only she knows who birthed them into creation so they could create all else. Out of all the Sisters, she seems to have the most influence on the mortal world as many cults try to curry her favour through bloody means but she seems to have ignored much of their placating and adoration.
One particularly old myth (which over the years has had T'Soarima replaced with any number of other gods that suited the current religious tastes of the day). The dwarven King Hymar of the Silver Marches wanted to take T'Soarima for a bride as his hubris demanded nothing else. To win her affection, he summoned her and showed her many prisoners of war that he had captured during a civil war affecting his land. He then executed them in her name. Enraged by this, she cast a thunderous storm and turned Hymar and the rest of the Royal Family into bears. She then called her hunting dogs, the three-headed dogs named Kroanasis, Lamethan and Wralla, and set chase. It is rumoured she still wears the pelt of Hymar to this day. She then had the prisoners resurrected and advised them to be of a more sensible mind than their king.
