In those days, Khadgar, Turalyon and the others led the Alliance into Draenor. As a result of other races wanting to protect their own homes, they also sent in their people to this land that was destroyed as far as the eye could see.
They built two fortresses in Hellfire. As for why they built two and not one, there was only one reason – the Alliance and the Horde would never be able to completely trust one another.
For the sake of protecting Azeroth from the Legion, they fought day and night for multiple days around the Hellfire Peninsula.
They needed to battle against seemingly never-ending waves of Scourge soldiers. A single team of people were definitely not enough. They needed multiple squads to rotate and defend.
In the beginning, one squad only needed to fight for one day. As their strength slowly dwindled over time, they could only rotate after a few days of fighting. However, rotating after seven days of fighting was quite unusual.
