I totally just replied to your thread. How strange :D but I think the Open thread was a great idea, so thanks for that!
Rauri is a bit stupidly brave, but he doesn't know whether that's stupidity or bravery because he's pretty selfless, but also someone who'd help someone else in need before himself. He and Griff are the same as far as survival skills are concerned though, and he only knows First Aid because it came with some free training he did.
I'm totally happy to offer lines for all the above, but I think he and Griff will get along the most ^_^
