She wants vengeance

Elena then stated with anger in her eyes, "If I going to do this, I want vengeance on those people that cast me out and sent me back to your dump of a cave!"

Kazex is actually taken aback by this statement, "you realize what your asking?"

Kisx"yea mom, aren't they your people?"

Elena smirked, "my people are honorable and would not cast out the weak just for getting caught by a stupid goblin."

Kazex didn't really like being called stupid, but he let it side for now, "not only that… you understand my brood is currently far too weak to undertake such a task."

Elena "then enlist help from other broods."

Kazex "This action could end in a war against the elvish. Far too great a risk for and brood father or chief to undertake without great consideration. And all I have of value would be you. I am not a sharing goblin, and I don't think you would like being shared to the level that would cover the cost of such a deal."
