Would Caelum be a viable mercenary? I don't know what Nav3 will look like, but from Nav2 it seems there's a limited options in terms of lending army muscle. Granted, the info, craft and other services are unhampered, though the actual "mercenary" service is difficult to bring to players. Flight would help

Another idea might be to give merc gate-stone, with the rule that gate-stone can not be used to teleport on player provinces unless permission was given, or usable only when solicited and paid for by a player. Or hell, maybe just no rule at all, as its a pain to enforce. Flying ship might be another one to throw in...

Just some ideas.

If land nation for merc is choosen, maybe set the map up to have its core holding locked in by border mountains, maybe with 2-4 pass or just the teleporting connection to edge of map (of course I don't know what Nav3 will look like remotely, just basing on Nav2). a Not so good idea may be to stick a sphinx (or whatever works) in each of those pass with a fort...

I'm not sure what setting/role/power/goal you have in mind for the merc in Nav3, so the above haven't really accounted for that.
