Stormwind Keep

From wow.incgamers.com

The Keep within Stormwind City, the capital of the Kingdom of Azeroth (now known as the Kingdom of Stormwind). Soon after the Dark Portal was created, the Orcs tried to take Stormwind and failed. However, after Medivh's death, the tides of war changed and Orgrim Doomhammer seized Stormwind after conquering the lands of Azeroth, sending the majority of survivors north over the Great Sea to Lordaeron.
