Skill against older warrior

While competing in the yearly contest held by the Elders of Chemos, Lucius’ impeccable swordsmanship caught the eye of a hulking stranger who watched from the shadows. During the last round of the Golden Sword, there was a disruption in the tourney lists, and the young swordsman found himself fighting against a famed champion twice his age. Though Lucius had proven himself the better warrior within the first few minutes, when his opponent drove a knee into his stomach, the youth was knocked to the dirt. Winded, Lucius reeled and stumbled out of his foe’s reach long enough to recover his breath. A frown of concentration on his boyish face, he then proceeded to take his opponent apart, limb by limb and vein by gushing vein. The champion’s supporters were outraged at the callous dispatching of their leader, and they stormed the arena en masse.

Enhanced beyond mortal bounds by the blessings of the Space Marine induction process, Lucius became ever more skilled in the arts of the blade.
