The following action he took baffled Solomon, and took Alexander by surprise.
Zagan stabbed his right hand into his chest, quicker than Sangis could react, and as he did, he grabbed onto his own soul and crushed it.
There was no agonizing cry, or drifting away of a life behind his eyes. His death was instantaneous.
But he died with a big grin on his lips, and his left hand in a show of bad faith toward Alexander.
Alex looked at the scene and wasn't sure whether to scoff or plainly laugh. This was extreme, even for a demon king.
Even the other kings were looking at Zagan's body, as it started burning away, with their mouths agape and their eyes wide.
Solomon extinguished the spell he'd been holding in his hands, knowing this was a useless endeavour.
"Zagan… You fool…"
But as the body burned away, a single pulse of Aether resounded in the ring's enclosed space. And Alex knew instantly why the demon had done what he did.
