Sacred:Sergeant Treville

Sargeant Reginal Treville is said to be a close confidant of Prince Valor's, at the start of the story he is the new commander of the defense forces in Porto Vallum and finds himself fighting goblins and orcs.

After you give him the letter of introduction of Commander Romata, he will send you to rescue Wilbur, the spy, who has been investigating an orc settlement nearby (Note: the English text in this dialogue wasn't translated from the final text of the game, but from a previous one, so in the English text he send you to speak with Prince Valor but the main quest indicator points to Wilbur)

Later in the game we find him again in Urkuk, he was mortally wounded covering Prince Valor's retreat. After giving him some water he tells us that the prince has managed to escape and falls dead.
