Enlightened One: leader of the order
Oath of the Delian order: I swear theDelian Oath. To serve Life, battle Death and strive to keep the Delian lore Secret.
The oath is not magically binding. It is a promise from oneself to oneself.
This is an order that vowed to protect the mundane world. Their mission is particularly concerned with the treatment of the Trinity artifacts: the Divine Eye, the Withered Hand and the Reality Cape.
They attempted to erase the three artifacts from the memory of the world since they could not destroy them. They judged that no mortal could wield the artifacts without bringing about the ruin of everybody. The items cannot be destroyed unless the divine power from which they come is itself destroyed.
The order is specifically not religious, they see themselves as the protectors of the Mundane world. They oppose Heaven in that it is it that sent the artifacts into the world and they see that as an inherently disruptive act.
There is a legendary set of armor and weapon worn by the leader of the Delian order: Dawn (battleaxe), Zenith (armor) and Dusk (Shield). They reveal their true power when reunited.
In order to make the world forget once again, there needs to be at least two people performing the ritual. One of the two will remember, the other(s) won’t.
