Give faction status

[Neiv]

I have several turn-in functions in which faction is granted for the turn-in. What I really need for one of them is to grant full ally status. I know ally = 1 in the 1-9 faction system. But I have not been able to figure out how to grant a "1" to a player. The quest::faction() function grants a faction amount, but does not grant ally status. I want to make it so that a player with a completely opposing faction can gain full "citizenship" into another "kingdom" (another faction) when he chooses to turn in a certain item to the king of that realm. The problem I have had is, if a player has a negative faction due with a realm due to killing the npcs of that realm, no amount of faction granting will be enough to make ally with that faction. Is there a way to grant ally status outside of granting faction?
