So, the lich king dies. Someone must take up his crown, to prevent the undead Scourge washing over the world, ravaging everything. Originally Tirion Fordring believes it'll be him.. until another, forgotten hero turns up to save us. None other than the legendary Bolvar Fordring. We thought he'd died at the wrath gate; not so. You can't keep a son of Stormwind down.
When he is given the crown, a blaze of light is born in the center of the icecrown citadel. Fordragon orders Fordring to tell the world that the Lich King is dead.
But he'll be back to save us one day. Through light and fire, where as the old Scourge represented shadow and frost.
That'll teach the Horde. For sooo long they waved it over us that they had Saurfang and we had peasly Fordragon. Now, Saurfang is old and boring, His son is dead and evil, and Bolvar is the new LICH KING.
I reckon this will spawn 10,000,000 new alliance recruits.
