Uredinum is the prized leaf-edged sword of Praepositus. Other than the un-cloned humans, it is the last pure artifact from the Earth of Praepositus and Aeturnus. Other than it's ownership from Praepositus, the sword experiences a relitively quiet existence until it is enchanted by TBS, giving it an internal burning effect. Desperately wanting back his sword, Praepositus tried to summon the sword. It works at first, but then Praepositus abandons the attempt claiming these 'powers' to be mere superstitions.
