Valen Shadowbreath

Valen Shadowbreath is a tiefling weapon master first encountered in the rebel drow encampment of Lith My'athar in Act II of Neverwinter Nights: Hordes of the Underdark.

Initially distrustful of the player, Valen nevertheless makes his services available, and is the romance option for female characters. Valen is a tremendously powerful warrior who makes a great tank for the player's small group. As a tiefling, or part demon, he is constantly besieged by the violent nature of his infernal blood and his dark past.

The player can choose to acquire Valen's True Name, "Oeskathine the Demonwrestler," near the end of the Hordes of the Underdark campaign. Before the final battle, the player then has a dialogue option to use Valen's true name to free him from his infernal taint, thus saving him from his own blood. If this is not done, Mephistopheles offers to do the same for Valen, and he will turn against the player unless:
 * a successful persuade check is made
 * he is compelled against his own will to fight with you (by use of his True Name)
 * a female player has built up a strong enough relationship with him.
