Months have passed since the Burning Legion's army was defeated. The Night Elves have returned to the Ashenvale Forest. The battered Horde has settled in the east of Kalimdor, along with the remnants of humanity. Arthas, the new king of Lordaeron, is not intent on stopping — driven by the call of the Frozen Throne, he aims to conquer the entire world.
And somewhere in a hidden corner of this world, hunted by his jailer Maiev, Illidan, known as the 'Betrayer,' is plotting his plans. His time has not yet come.
The ancient race of Naga is awakening at Illidan's call. The High Elves, stripped of their source of power, are preparing to embark on a quest for new strength.
The Nagas and the High Elves will unite to stop Arthas, who is determined to become the king of the Scourge army.
