"Theramore's Fall" refers to a significant event in the lore of the game series World of Warcraft. It marks the destruction of the city of Theramore, a stronghold of the Alliance in the region of Dustwallow Marsh. The event occurs during the War of the Ancients and is a pivotal moment that escalates tensions between the Horde and the Alliance. The fall of Theramore is orchestrated by Garrosh Hellscream, the Warchief of the Horde, who uses a powerful mana bomb to obliterate the city. This act not only results in the loss of countless lives but also serves as a catalyst for further conflict in the ongoing war between the two factions.
