Once upon a time there was a Miner who lived on Cake Island and who found enormous reserves of magic underground. He had a magic rat to warn him of coming rockslides and gas leaks, and it would follow him everywhere.
The rat was the Miner’s only friend, but he began to suspect that it wanted to steal his magic and chased it away, just in case. His greed exhausted him so much that his body shriveled up and he turned into a skeleton that had neither a heart nor a brain, and he couldn’t use his magic wealth anymore.
Ever since then, the Greedy Miner has wandered around the island and pestered passersby at night, demanding that they return his rat. If you talk to him, he will follow you home and moan under your window, “Where is my darling rat?”
