Divinity: Original Sin 2: Lucian the Divine

Among the mortal races — most notably humans and necromancers — some began to worship the Lord of Chaos, creator of demons (the forgotten eighth race), under the name Legion of the Damned. After being nearly exterminated by the representative of the Wizard race, Ruben Ferol, and the Seven Gods, they went into hiding, scheming in the shadows under the name Black Ring, eventually shifting their devotion to the God King. Those who swore an oath to the God King gained the ability to control the Source, as well as to return to life after their death in the form of an undead, in order to continue their purpose. Only the Swornbreaker, a one-of-a-kind scythe, could possibly break such an oath.
Years later, they waged war against Lucian the Divine*, representative of the Seven Gods, and his Divine Order — and were defeated.

Since his ascension as Divine, Lucian had been worshipped as a god by the seven mortal races. He founded the Divine Order, a powerful military organization composed of various divisions of soldiers, warriors, nobles, and paladins. Later came the Magisters — the largest division, made up mostly of commoners — and finally the Seekers, whose unwavering devotion was focused on protecting the ideals and lands tied to the Seven Gods.

Before becoming Divine, a person may be chosen by their patron god to become Godwoken. Their god allows them to absorb and use Source to a certain extent. If the Godwoken succeeds in passing certain trials (such as the Path of Blood), they may ascend to Divinity, becoming the representative of the Seven Gods. Their power surpasses that of any other Godwoken, though still beneath that of a true god, as they remain dependent on them.
If the Divine dies, the Gods each choose one or more heirs, thus appointing several Godwoken capable of taking the role. In the end, only one may ascend.

This time, Lucian the Divine used a deathfog bomb to wipe out the members of the Black Ring — but in doing so, also annihilated much of the elven people who had given them refuge.
At that time, Ifan ben-Mezd was a young crusader full of ideals and justice, serving in the Divine Order. Lucian sent him specifically to the elves, to offer them a portal for evacuation before the bomb was triggered. Unfortunately, things did not go as planned. Ifan managed to escape, but failed to save the elves — those who had saved and raised him when he was just a child.

The near-total extermination of the elves greatly weakened the power of Tir-Cendelius, which in turn weakened the Veil separating Rivellon from the Void. The remaining Source of Lucian and the Gods was no longer enough to maintain the Veil. As a result, Voidwokens began to cross over and invade the world.
The Voidwokens were, in truth, the Eternals — transformed into Void creatures after being banished there by the Seven Gods, and sent by the God King, still sealed away.

Le plan

To restore the Veil, Lucian devised a plan: he needed to acquire as much Source as possible from the Seven Gods. To do this, he resolved to kill all living Godwoken and hunt down anyone who could potentially become one — hiring Roost Anlon of the Lone Wolves to track and kill potential heirs to the Divine throne.
To assist him, Lucian sent his own son, Alexandar, himself Godwoken, to lead the Divine Order. Any person sensitive to Source — a Sourcerer — was arrested and sent to Fort Joy. Most of the time, making use of the Source would make the Voidwokens come.

Lucian faked his own death and hid in a chamber beneath the Divine Throne. His apparent death was so convincing that even the Gods believed it, and began guiding new Godwoken toward the supposedly vacant throne.

In the end, Lucian’s goal was to absorb all Source for himself, surpass the Seven Gods, and restore the Veil.

Lucian appears both in Divinity: Original Sin 2 and in Ifan's backstory in the graphic novel « Godwoken » from Larian Store.
