Where Dragons Fell

Becomes available after completing "Futility"

Leads to "Time for Answers"

Taken from WoWwiki:

Long before the Great Sundering, the five dragonflights - red, blue, bronze, green and black - were charged with watching over the budding world of Azeroth. Sindragosa was the beloved consort of the blue dragon Malygos, also called the Spell Weaver, guardian of all arcane magic. With the help of goblin servants, Neltharion created a powerful artifact called the Dragon Soul. He convinced his dragon brethren to empower the disk, claiming it would thwart the impending invasion of the demonic Burning Legion.

However, Neltharion betrayed his dragon allies during the Legion's assault, provoking a apocalyptic battle in the skies over the Well of Eternity. Malygos and Sindragosa joined the blue dragons in surrounding the Earth Warder. They charged the black dragon... But Neltharion used the might of the Dragon Soul to strike out, decimating nearly all of the blue dragonflight. The blast hurled Sindragosa far across the land, deep in the the frozen north.

Blinded and near death, Sindragosa sought desperately to reach the Dragonblight, the place were dragons instinctively travel to die. No longer able to fly, Sindragosa plummeted to the cold earth in the region of Icecrown. The blue dragon gathered what remained of her energy and called out to Malygos for aid. Her only answer was the howling arctic wind as she struggled on, but the distance was far too great; agonizingly she realized that her spirit would not find rest with the Dragonblight. Her life continued to fade away as her sanity deteriorated.

In the midst of her delirium, Sindragosa's final thoughts turned to bitterness and hatred: hatred against the Legion, hatred against Neltharion, hatred even against Malygos. But most of all, hatred against the world of mortals.

And in her dying moments... Sindragosa vowed revenge.
