ORGA!!!!

If our hero actually end up defeating the whole goblin tribe all by himself he's going to end up in the middle of his new eager (if somewhat terrified) goblin harem.

He's going to get all the sweet goblin love that he can wish for and then some more.

And with his help the tribe gets new blood. Stronger blood. More women and stronger men.

The rules will be the same for the renewed tribe, but the men that made it possible will be an exception. He's going to be the daddy for a new generation of goblins than the daddy for the generation that comes after that, and for the one after that and so on. Until old age or bad luck takes it's toll.

The tribe wins eather way. Really.
