So... could the grave that Silver was at actually be the grave of both Gray's father and mother?

With them buried in such a cold land, their bodies would decay much slower so that could be used as an excuse how Silver's body looked so intact (either that or he used the timeskip to find some good plastic surgeon). After being released from the ice, the bodyless Deliora went back to the place where he was defeated, somehow found that grave, dug up Silver's body and took it for his own. And then he occasionally visited this place where he got this new body for some sentimental reason.

But it still makes little sense. When Deliora destroyed those villages it didn't use ice magic, so why did it's magic suddenly change? Is it multi-elemental like Tempesta?
