There are two types of runes.
The first type was made up of ordinary runes, whose power to complete their work was imbued by their creator and did not need an external source to function.
The second were the so-called sacrificial runes, which worked by a mechanism that sucked in the energy of a sacrifice, which could be anything from mana cores to living people, then redirected this energy to fulfill the role defined by its creator.
Above these runes, there was a deity: Runelord, the god of runes, a being whose power was far beyond anything the Eternal Isles had ever seen in its existence.
But although he called himself the "God of the runes", the runes were not created by him, nor did they even depend on him.
He was more like a parasite, an ancient specialist who learned to channel and use a part of all the power imbued in the runes around the universe and, abusing this stolen power, ascended to divinity.
