as the player progresses along the auroran and polaris storylines, he encounters the thurokiir, the obsidian heart or spiritual master of house heraan, techerakh the bloody hammer. if following the auroran storyline, techerakh renames your character karhallarn, or the wolf. both titles, one as thurokiir, and one as a fleet master (karhallarn of the pack) symbolize the aurorans' deep respect for clan-warfare and battle honor. similar to east asian countries of earth from the dark ages to mid-1960s, the aurorans build their society around "face" and "shame." to flee from battle or surrender to the enemy is an atrocity against one's empire, house, and self. thus the aurorans provide one of the most complex factions in "nova", due to the intricacies of their warrior society.
