The Crois Family (クロイス家) is a historically influential family in Crossbell.
Prior to the Great Collapse, ancestors of the Crois Family were given the Sept-Terrion of Mirage. It bestowed knowledge upon the family, hoping to assist them in guiding their faction. When Demiourgos realised its knowledge was merely abused, it decided to cease its own existence. Since its disappearance, the Crois family feared the loss of their power and dedicated themselves to creating a replacement for the centuries following the Great Collapse.
During the 8th Century, they decided on alchemy as their method of choice and prepared a plan that would span multiple centuries to complete. They formed the D∴G Cult and entrusted it with the core, a homunculus referred to as KeA capable of containing the reborn Demiourgos. While the D∴G Cult was tasked with awakening the core, the Crois family themselves focused on banking in order to gather the financial resources necessary for the final phases of their plan.
