Nona, Horn, and Corudan
My idea is a wee-bit lore breaking (Corudan) but fighting alongside Nona (possibly not if she doesn't come back, or she dies along the epics) Horn and Corudan in one of the Instances (or what not ) would be so Awesome! It could even lead to the Deaths of Nona and Horn as Aragorn, you, Corudan, Legolas, Gimli, and the rohirrim flee to the Keep after the wall is Blown up.
They could cover your retreat and at the end of the Battle you find them dead with Uruk and Orc bodies all about them, even a session play where you are one of them. Would be very cool but Corudan would be lore-breaking as there where no elves (or dwarves or Hobbits, mind you) but then again having our real characters at helms deep is also lore-breaking but who cares? (not me!) Also somehow having Morflak alive and you have to kill him once and for all would be kinda cool but also weird? Anyone else have any ideas they'd like to share?
