Two Leaders (Tord x Reader)

The Red Army is under attack and is running out of resources. The Red Leader's only chance to save is army is to turn to another for help.
The Gold Army.
Tord has never been one to turn to others for help, but in this case, he has to. He doesn't have enough men, enough funds and his soldiers are running out of hope. His last resort is turn to you for help.
Y/N L/N. The Gold Leader.
He's not to keen to ask you for help, but with his men dying, his food running out, what choice does he have other than to ask for help from one of the most fearsome Leaders out there, possibly rivalling even himself?
What makes her so formidable is that there is very little known information on her. Her name, the fact that she's alive and the common knowledge that she should be left alone, unless you want to be destroyed, is all that's known about her.
But Tord has no choice except to ask for help.
