It's oftenly said that the Old God's corpses are giants, and i was wondering : could C'Thun still be alive ? I mean, the only thing we seems to have killed is an eye, some tentacles and a stomach (He could have more stomachs than one). Also, when we bring him elementium ingots, Arygos states that the elementium is an element created by the volatility of C'Thun.
And what was the main mineral in Cataclysm ? Elementium.
Doesn't it implie that C'Thun is still alive ?
Also, Elementium seems to be the equivalent for Northrend's saronite, made of Yoggy's blood.
