he tried to kill Inferno but was stopped by Kaosa, who spirited Inferno away with the aid of other Dragon Aspects - Ebonscale, not wanting to waste a full-chase with Kaosa (and risk a war with the other Dragon-Flights before he was prepared for it)  cursed Inferno with a specific immortality.. as long as either lives, neither can die..

"very well, let the whelp live.. as long as he lives so shall I.. father and son, bond in time.. my Essence and his.. this I decree, this it shall be.." - Ebonscale
