I'm looking for a comic about a kid that gets lost in the woods and finds himself in a fantasy world, but the story focuses on how the loss of one of their kids ruins the lives of the parents for most of the first issue. It ends with the son returning as a full grown adult like a year or two later due to magical time dilation, but an evil wizard he fought in the fantasy world is plotting to invade the "real" world. I remember it was a western comic with a very generic title like "The Legend Returns" or something, which has made tracking it down a pain cause google just brings up a bunch of isekai shit.
Pic semi related. The kid grew up to be a big Conan lookin' motherfucker, but he had a long black beard.
