Rey Yan is the fictional protagonist of the manhwa series Chronicles of the Cursed Sword by Yeo Beop-Ryong and Park Hui-jin (art).
At the "Gigantic Pagoda" where the Prime Minister resides, all the orphans are locked in a dark room, and each is given a sword.
Being told that they would have to fight if they wanted to get out, they fought for months and the children became relentless, greedy, and violent, driven by the scarcity of food provided to them.
After some time, Master Loruan and his disciple, Shyao, found Rey, holding the Pasa sword.
Loruan sacrificed himself using a forbidden spell for Rey and Shyao to escape with the Pasa sword.
After Shyao's betrayal, he retreats into the mountains and becomes a listless wanderer, barely even interested in killing the demons there for a time.
He is quick to anger but doesn't hold grudges... Making new friends has made him a mellower... Hui-Jin also reveals that Rey 'has a soft spot for women' and can be a bit shy around them (especially Shyao).
One such technique is "A spell to shatter diamonds," in which a giant explosion is created by harnessing the earth element.
