Thaddeus appears to be an immensely large half-orc or orc, standing at around 6'10" and with over 300 lbs of pure muscle he is certainly an imposing figure. He has long black hair which he usually keeps in a messy ponytail, his eyes glow of crimson and he has ears like knife tips. His voice is deep and depending on his mood he might interject growls into the conversation. Thaddeus has a slight temper but is usually friendly with allies and acquaintances, he enjoys drinking, fighting and competing.

Thaddeus is known by many titles including but not limited too; The Crimson King, Lord of Murder, Patron Saint of Killers, God of War. His worshippers used to be quite varied but the most common ones were assassins, barbarians, soldiers and hunters. Although Thaddeus is most definitely a bloodthirsty deity it is not necessarily a malevolent kind. Thaddeus despises the killing of those unworthy like children and kind folk, he is more about the glory of combat itself and can actually be friendly unlike some other Gods of War. Thaddeus has slayed many beasts and monsters, some Gods respect and like him but others despise him for his foul language, his barbaric nature and his penchant for drinking.
