Sooo what was the unexpected betrayal Strongbow had to face? His kids moving out? A youngster (Ember) being of his opinion? He's a wuss! I'm pretty convinced the souls of the dead immortals (can, if they choose to) return to the original homeplanet. What else could break them from the bound with the palace? And all the dreams of of dreamtimes had probably some foreshadowing meaning. So Treestump might end up creating weapons which will turn against the elves. The new hold might get destroyed again (although this kind of definite destruction already befell the Thorny Mountain Hold). Maybe the Clearbrook will get stuck in the (symbolic) caverns :'( . Who knows?
