here, have some Adri

This is Adri, he's Rinnie's twin brother. If you can read my scrawling handwriting, you'll see that it says he has an infectious, or parasitic stone growing in and over his arm. It's a special type of stone that digs it's way inside it's host and starts to grow - much like a parasitic fungus. Luckily, it's effects take place much more slowly since it's stone.
