"Thomas (トーマス, Tōmasu?) is the master of Budehuc castle and 15 years old during the events of Suikoden III. He was born in the Northern Outlands and lived with his mother. When his mother died, he went to the Grasslands to find his father, Lowma, who was a member of the Zexen Council. Lowma did not give a warm welcome to his illegitimate son whom he had no use for and could damage his reputation. Seeking to remove him in a way that was at least honorable on the face for a nobleman's son, Thomas was made master of the rundown Budehuc castle. Thomas greatly doubted his ability to manage the castle initially.
Soon after Thomas arrives, he finds that the finances for the castle are extremely small, explaining the poor upkeep of the grounds. Not wishing to reduce an already depleted staff, Thomas embarks upon a scheme to attract more business to the castle. Martha, an older Grasslander, recalls when business thrived and the castle was a free trade zone between Zexen and the Grasslands. Thomas decides to seek out merchants to come set up shop at Budehuc, realizing that this would probably bring down the wrath of the Zexen merchants on a competitor biting into their sales. Thomas and a select few servants- Cecile, Piccolo, and Juan- set out to inform others that Budehuc is welcoming anyone who wishes to open a shop there. (Through cutscenes, Thomas can meet all three of the other main characters and convince them to also inform travelers that Budehuc is looking for shop owners).
The later parts of Thomas's chapters deal with the Zexen Council sending their knights to interfere with Thomas's plans. Thomas is eventually asked to give the castle a new name, since no one could pronounce "Budehuc" correctly and Thomas was the real owner of the castle after standing up to the Zexen Council. Eventually, Thomas offers his castle for use by the second Fire Bringer in Chapter 4 after the Harmonian attack.
Thomas is the chronological successor of the Hero from Suikoden II as the Tenkai Star, the first position among the Stars of Destiny, traditionally held by the main character in the Suikoden series who have the task of gathering the remaining stars under their lead. Whereas his predecessors were all distinguished war heroes, Thomas creates a contrast by playing the role of a normal person who does his best within a difficult situation, as he not only has no real military expertise nor does he bear any special Rune, but he is also not designated as the leader of the eventually formed army. While the other viewpoint characters start at more elevated levels, such as Hugo at level 5 and Chris at level 20, Thomas and Cecile both start at level 1.
In combat, Thomas uses a sword. He has a combination attack with Cecile entitled "Best Effort" which leaves Thomas unbalanced."
