Finnish game
designer.
Author of both
Mordheim and the 6th edition
Warhammer, which came out in the fall
2000. For the 5th edition he wrote many
supplements for the game, such as
Realm of Chaos and
Warhammer Siege, and also co-wrote such books as
Vampire Counts,
Dogs of War and
Warhammer Magic.
After writing the 6th edition of Warhammer, Tuomas left Games Workshop and joined an IT company, apparently because "they pay more".
