To be honest I didn't think the new jobs would get relic weapons. However the relic weapons 2.0 do not have to have anything to do with the zodiac Braves. Honestly I don't think it would make sense to go any further with the zodiac weapons. My money is on the new relics being completely new lore perhaps even having something to do with thordan and his 12 knights or maybe even the ancient civilization that exsisted back in the time of saint shiva.
