I've actually got a 4e character I keep trying to play (well, not actively in the past few years, but still) that leverages this horror.
See, there's a Theme (effectively the crunchy parts of 5e Backgrounds, for folks who never played 4e) called "Ghost of the Past." The Ghost from the Past theme is that, by whatever mechanism, your character is from a long-lost era of history. Everything they knew is gone, whether vanished completely or decayed into ruin. You get History training (or any other skill, if you already have History trained), and the Guidance of the Past Encounter power (effectively, advantage on any d20 check, but if the dice come up equal, you're Dazed UEONT, which is a pretty nasty condition in 4e.) It's really fun, and I love that it's just dripping with flavor and roleplay potential. It isn't particularly powerful, but it's got some neat features. (One of the alternate utility powers you can take at level 10 literally lets you disappear from time for a couple rounds.)
The version I've gone with is the character went out to deal with an unknown monster terrorizing the land...and it ended up being a medusa or some other petrification-causing creature (perhaps a classical basilisk) and got petrified. All his comrades in arms either died or escaped and couldn't save him, so he's been sitting in a cave (protected from the elements!) as a statue for centuries, until someone else comes along, discovers him, and is kind enough to free him from his stony form. Now he has to figure out how to put his life back together and fix the ills that plague the present--and decide whether he wants to stay in this dark future or return to a past that may already be beyond saving.
