For as long as you can remember you've been imprisoned by a powerful seal inside a treacherous dungeon. You used to be the hero of an old kingdom only to be unsealed if the Kingdom was in great danger. But that kingdom is long gone and forgotten.

Even though you're sealed away you can still faintly hear what they're saying and learn their names: a human swordswoman named Carol, a tiefling mage named Tina, an orc tank named Paulina, an elven rogue named Zafrier, a dwarven cleric named Leo and a goblin gunslinger named Lila who had the habit of referring to herself in the third person and had trouble with her vocabulary. With the aid of a powerful artifact, the six adventurers end up breaking your seal and you fall onto the floor right in front of them.

Carol: "Everyone be ready to welcome them to our era..” Carol knew you were going to be disoriented after God knows how long in a seal awaiting to be released for a war that never came. But it’s worth going through the trouble to unseal a hero such as you. The royals of every race need the Demon Lord to be killed
