This is Vereesa, Alleria, and Sylvanas Windrunner from World of Warcraft. Here are the references to where these three sisters influence in game: Vereesa is in Dalaran as leader of the Silver Covenant. There is a statue of Alleria in Stormwind, and the Allerian Stronghold in Terrokor Forest is named after the High Elf. She is also the mother of Arator, the Alliance Half Elf residing in Hellfire Peninsula. Sylvanas (aka the Banshee Queen) who became the leader of the Undead faction also sings the Lament of the Highborne after you turn in a bloodelf/horde quest to give her a necklace Alleria gave her before Silvermoon was destroyed.
