The Ruins of Lordaeron is all that remains of the City of Lordaeron, the great capital city of the Alliance. Now it serves as nothing more than a sad reminder of the power of the Scourge. The area is literally haunted by the final tragic events that led to the death of King Terenas and the city's destruction.
To this day you can still hear the moments before King Terenas' death; hushed whispers in the courtyard, the clanging of bells in the entryway, the faint cheer echoing the welcome of Prince Arthas, and the murmur of voices in the throne room. One such sentence that is uttered says " This kingdom shall fall, and from the ashes shall arise a new order that will shake the very foundations of the world." — Arthas after slaying his father, and proclaiming the Scourge's invasion and victory over Lordaeron. If you can detect invisibility, you will see the ghosts of the citizens of Lordaeron still haunting the castle's courtyard. Beneath the ruins now lies the Forsaken capital city — the Undercity, where the dark queen prepares to reclaim her lost lands to the east.

Undercity is beneath Lordaeron’s ruins, but above the Forsaken city one can visit Lordaeron’s palace. Terenas’ throne room and the royal crypts are still intact. The bloodstain where Arthas slew his father can still be seen. The magnificent gardens are also accessible, though they have grown wild and play home to lurking beasts.LoC 109 You may also even hear the voices of the cinematic at the end of the human campaign in Warcraft III: Reign of Chaos.
