Aiden had just begun to consider this possibility when he quickly realized it was unlikely.
Five years ago, the Blood Moon Cult led by "Mr. Bloodclothes" from behind the scenes had been thoroughly dismantled by the heretic inquisition of Silvertown, and all cult members apart from the mastermind himself had been killed. Even if there were other remaining affiliates, after being thoroughly investigated by the inquisition and another five years passing, they should have long since scattered like birds and beasts.
In other words, for Mr. Bloodclothes, the banner of "Blood Red Full Moon" no longer held any value. Raising it again would only alert the inquisition, bringing him harm rather than benefits.
