|Full Name:||Sir Cassian Marks|
|Birthplace:||Illikon, Northwestern Empire|
|Affiliations:||Achaean Empire, House of Marks, Illikon|
As heir to one of the most important houses of the Northwestern Kingdom, Sir Cassian Marks is a powerful man in Illikon - a city he staunchly defends with his life as a knight. When he married the eldest daughter of the House of Draconius, he put himself into an even stronger position in the Kingdom, with only the adopted bastard Tom Drake standing in his way to inheriting both Houses Marks and Drake.
Cassian Marks is a handsome, noble, brave, and important man - and he knows it. Extremely proud, he frequently butts heads with Tom Drake, whom he considers a brash lowborn lout unworthy of his station. Despite his often abrasive personality, Marks is very loyal to Illikon and fights fiercely to defend it against barbarian invaders from Northrim.
