The inhabitants of his village removed his arms and legs to keep him from ever leaving, all while revering him as a deity for their own convenience. Crimson Moon took note of this, and challenged the villagers to a morbid game: all throughout the night, the villagers would have to imagine beasts for Merem to materialize, and if none of the creatures were able to defeat him by daybreak, they would all be slaughtered.
Nothing from their imaginations could possibly stand up to Crimson Moon, so he kept his promise and killed all of them at dawn. The act of materializing the beasts was too much for Merem to bear, which lead to his death. He was revived by Crimson Moon as an Apostle and told, that as he was now free of his captors, to imagine beasts to replace his lost limbs. Merem feels an immense sense of gratitude towards him, which he has directed towards his golden princess, Arcueid, since his destruction.
