The 13th?

If I recall, in the 5.3 story quests, it is noted that Warriors of Light and Hero tends to be used interchangeably. It does leave some credence for Cuchulainn being a Warrior of Light. I do believe we are also refered to as a champion on occasion.

While that was specifically regarding the heroes from the First, I guess it could also be ascribed to the other champions from other Shards.
