Might As Well
The Cult of Starry Skies.
A mysterious religious organization that has existed since even before Mana descended, having a long-lasting history with influence that goes so deep that most people don't even know just how extensive it truly is.
Many had tried to destroy it in the past, and a few had come close, but none had ever succeeded, and as time passed, they only grew stronger while others became more wary of their existence.
Even before Mana descended, they were known to have strange methods towards almost anything. Odd, ancient techniques that defied logic were things they deployed frequently and were used to either assert their dominance or ward off potential threats.
When Mana descended, they were among the first group of people to take advantage of the fact, almost as if they had been waiting for that moment, and they quickly established themselves as a powerful, albeit reclusive faction.
