When blacksmith apprentice Sand wakes up in a ruined castle, he has no idea how he got there, but the thorny brambles that surround the walls prevent him from leaving. As he begins to fix up the castle in order to survive, everything he touches somehow works better than it should. Then, as he continues to explore, Sand discovers the castle’s secrets, including its long lost heir, Perrotte. Together they must fully repair the broken castle if they ever want to leave.
