Maragan is a Nodon dragonkin. Back when the Dragonkin still lived in Orthen, he was an elder of his faction and a representative in the Kindra council.
Thousands of years ago, during a Kindra council meeting, the different dragonkin factions met to discuss how to deal with the Elder Gods, each one proposing a different plan. While they could not reach consensus, every faction agreed to carry on with their plans while maintaining everyone else informed of their progress. Kerapac, who was a fledgling in the Dactyl faction at the time, did not keep his word and carried on with his plan without approval from the council. As a result, an enraged Jas destroyed Orthen and enslaved the dragonkin, binding them to the Stone of Jas.
Some time after this, the Nodon carried out with their proposed solution: to enter a state of prolonged hibernation in order to sleep through the curse. To this end, they built a hibernatorium in eastern Orthen where they could enter a shared dream. While Daraval was against this, the Nodon proceeded with their plan.
While it is unknown what became of the island where Orthen was located, in the Sixth Age Kerapac took control of the Needle and used its power to bring a past version of the island into the present in order to carry out his plan to destroy Gielinor and the Elder Gods with it. While searching for Kerapac, the World Guardian, with the help of Hannibus, located the hibernatorium and entered the Nodon's shared dream to learn more about Kerapac's plan. However, Maragan and Daraval were able to notice the intruders, who proceeded to explain their presence. Seeing that Kerapac once again was taking matters into his own hands, Maragan conceded to Daraval that perhaps they had slept for too long. The Nodon then explained the consequences of Kerapac's actions to the duo.
