Once a mortal healer by the name of Lenowyn, a name she is still called by some of her worshippers, Tria spent her mortal incarnation trying to negotiate between warring factions. She was so selfless and so caring that the good gods took notice of her acts, and made her one of their number. She is a goddess of diplomats and healers, who bestows her blessing upon those who seek to bring an end to strife and remedy the hurts of war. Those who worship her in this capacity in the present age are frequently considered weak and foolish, for it would take far more than an army of her devotees to persuade the forces of darkness to respect a balance of power and not seek more for themselves. Even those who fear the rising power of the Chaos Gods are more likely to turn towards a forceful deity like Melisande or Brem than to this unfashionable goddess.

As the Guardian of Eternal Peace, Tria's influence is harder to avoid. It is Tria who gathers up the spirits of the dead and guides them to their final rest. Because she will not take sides amongst the gods and risk disrupting the fragile illusion of peace among them, she alone is trusted to usher newly fallen souls to their eternal damnation or rewards. She manifests as either a featureless vision in a three-rayed crown, or as a minotaur with three horns.
