Plus, Magthera said she wished to see the undead and their curse lifted so the tauren took pity on the undead. This alliance was made out of Pure Convenience, with the horde Backing the Forsakened, the Alliance dared not to purge Lorderon at that moment the horde would attack them, so the Forsakened need not to worry about immenant death thanks to the Horde. The horde got a stronghold, and a way to hold their place in the Eastern Kingdoms, as well as mages that they really lacked at the time. Note this is Vanilla lore. At the moment, the Forsakened cannot be trifled with, so its now more than a convenience.
A way For the naga to enter into an alliance with either the Horde or the Alliance, is through an alliance of Convenience. What do the the Naga have that the others do not? What does the alliance and the horde have, that the naga do not? If a clan of Naga is betrayed by their queen, I am sure as hell they would go their enemies to seek Refuge. Now why would they take them, you might ask? Intelligence, pure and simple. At this moment, we have no idea what Queen Azshara is up too, and since she is deep within her city, why would she tell any of the land dwellers. The Naga that join either side could simply be traitors to the Naga Crown, but could very well be our saviors?
