What would you like to see out of the Mount Targon scene?
Presently, only Leona, Pantheon and Diana come from the Rakkorean race, and no other known Champions are presently associated with Mount Targon. Though Riot might retcon some to be part of the faction, I think we need some more original Champions to fill in the gaps.
To that end, what about Harpies? Wouldn't they make a suitable "archenemy" of the Rakkoreans? They'd certainly give Pantheon something to kill with regularity (rather than attacking Noxian patrols; that might draw the wrong kind of attention).
Brave, dauntless, never backs down from a fight?
Spear wielder?

could be moved to Mt.Targon,since the IoW doesn't exist anymore,but his old tribe is dead too,so he hasn't really many places to go.
