Imrai

Magic comes at a cost. After the First discovered the initial seams of otherworldly power, they very quickly began to utilize it in every aspect of their lives. They didn't learn of the cost until too late, after their entire societal structure had incorporated its use. Their fall was slow and insidious, like a viral infection. Slowly but surely, things went sour. Cults sprung up inside the existing places of worship, their parishes slowly succumbing to dark influences.   By the time the ruling castes began to take note, the infection had taken deep root across the planet, in every town, city and village, the dark influence grew. With every corrupted soul, the darkness increased in velocity and power, until there were only a few last bastions on the planet free of the corruption.
