Are You Taken?
The Great One Zaraya. Among all the Great Ones, he was said to be the leader and the strongest of them all, according to their history at least. He led the other two Great Ones to travel the unknown space to locate a higher world and managed to come back 100 years later with possible knowledge from it. And he's possibly the reason why the Dark World converted from being a Transcendent Created World to an Invasive World.
His current influence at the present Dark World was the highest among the six Great Ones. Having seven tribes under him, any Dimensional Space that appeared in his territory was all dealt with easily. Thus, it led them to grow prosperous throughout the years that passed.
