I found it at dragon's lair on 2/1/15.
No way to really know for sure that it's yours. But most of us are to lazy to concoct anything other than the truth. Let me know if you recently lost your rulebook.
My number is in my signature and it'll be on my person Thursday and next Sunday. After that I'll turn it over to dragon's lair.
I know we're not all on the forums, but if your friend or whatever lost they book, holla.
