From the meet-n-greet:
Cursed by destiny, Chain has lived a thousand different lives, and remembers them all. Chain began this eternal cycle by defeating the Dark Lord in a distant, possible future. With the help of Queen Ezmera, ruler of the Kingdom of Wugin, and the Crystal of Time, Chain sealed the three of them within the Crystal for all eternity.
Unfortunately the spell was imperfect, and the Dark Lord escaped back into reality, shattering the Crystal of Time into thousands of shards. Queen Ezmera and Chain were hurtled back in time to relive their mission once a century. After countless quests and lives, Chain will eventually return to his present and defeat the Dark Lord for a final time. Until then, Chain collects magical artifacts, explores temples and dungeons, and searches for a way to repair the damage done to continuity.
