Zayla Eternal Devari's Immortality

After the horrible events that occurred before Zayla was captured by Devari, she seems to have lost all hope. As far as she knows, the man she grew up with, the one she loves with her heart and soul Bodoku, is deceased. As well as her dear friend Tidus. Thinking that her remaining friends lack the strength to save her she has given up and resigned herself to becoming her uncles lab rat...
On the other hand, Bodoku is on the march to gather a small army in order to save Zayla, and prevent Devari from becoming immortal, but who is the mysterious masked man who keeps thwarting his plans and getting in his way...? And why does he wield the electric and fire powers that Zayla possesses?
