It is unprecedented but I would seek to work with you on two matters as we both can bring something to the table. The first is the issue of the magic eaters, beings that virtually make you useless if they appear. We can end them for good with both of our knowledge (the druidic and the book knowledge). The second is the Lich. I simply ask that you share the exact details of what the Lich took when it wiped your forces aside with ease. If you would be willing to share information on both, I would be willing to share what I know.
