Gandalf zapped this bit of info straight into my mind (zen-mail) here is this week-ends Hall of Fire Chat topic:

The Silmarils: What would have happened if Feanor had given the silmarils to the valar for the healing of the two trees? Would Morgoth have made war on the valar? Would he have had just counted his losses and got to some new evil?

Bring your copies of the silmarillion and get ready for another round of The Hall of Fire! Join Gandalf, Balin, Tookish and Gamgee Saturday January 29th at our new time: 5:30 EST. Special thanks to Berendir for this weeks topic..couldnt have done it with out ya man!
