Anyone know how long those in the supernatural world tend to live for? The Great War was said to be an eternity ago, and some like Mephisto and Zekram were around for it.

I've often seen characters mention millenia in regards to their lifespans, but I'm getting the feeling that's barely a dent in how long they live since Ddraig himself said Devils live nearly forever, and many millenia seem too small for that.

My current guess is they could live for millions of years possibly, but I can't tell if that guess is too much, not enough, or around the right number.
