Gary,
How do I go about making sure whether or not a word/name of a metal in your World Builders book is open content or not? It isn't specifically listed in the OGL declarations but it may be included under the general statements.
My wife created a metal just like that but we never had a name for it. So I just want to use it if possible and I/we actually get our adventure published. Its on page 107, Xagium. Plus it appears to be a variant of your name, at least when pronounced.
If it isn't OGL can I have your permission to use it in my module submissions? If I can, who do I contact to get legal proof of your permission?
I've already said it, so I'll just say I hope your birthday was a very pleasant one with a great game, or five, having been played today.
