The Fourth War, also known as the Blood War, is the global war between the Alliance and Horde following the third invasion of the Burning Legion and the Argus Campaign.After the mad titan Sargeras wounded the world, Azeroth's very life essence started bleeding to the surface in the form of an extraordinary material known as Azerite. Both factions recognized its unique properties, but while King Anduin Wrynn sought it to heal and protect, Warchief Sylvanas Windrunner saw it as a weapon and an opportunity to seize.
The tensions between the two superpowers rose and led to the War of the Thorns, where the Horde destroyed Teldrassil, one of the Alliance's major capitals. In return, the Alliance launched the Siege of Lordaeron, resulting in the ruination of the Undercity. Both factions now seek the destruction of the other in a war spanning the entire world, and recruit new allies to bolster their depleted ranks.
While the Alliance and Horde are the main belligerents in the war, the promise of the Azerite's power has also brought numerous independent powers into the conflict. These include, but are not limited to, the Ashvane Trading Company, the Venture Company, the black dragonflight, and the Old Gods' forces.
Following the betrayal of Sylvanas Windrunner to the Horde, the war began to de-escalate. The Fourth War had met an end in the form of an armistice; though a formalized peace between the Alliance and Horde was ultimately blocked by Tyrande Whisperwind, who refused to sign the treaty
Major Fronts of the War
War in the Eastern Kingdoms
A major front of the war, the Blood War conflict in the Eastern Kingdoms takes place mostly within the subcontinent of Lordaeron following the battle for Lordaeron Keep that saw the Undercity and the outskirts of the Ruins of Lordaeron devastated by Forsaken blight.
With the Alliance in control of Tirisfal, Gilneas, and the Plaguelands, the Forsaken began fortifying their positions in Silverpine and Hillsbrad from the Alliance’s encroaching armies. Horde forces fleeing from Tirisfal scouted out the ruins of Alterac City, Strahnbrad, and Durnholde Keep to rebuild as new Horde strongholds. Fenris Isle found itself in a constant tug of war between the Forsaken and the Gilneans. The Horde has claimed Shadowfang Keep, where the Royal Apothecary Society began working on a new plague to blight Gilneas with, but the 7th Legion soon had Shadowfang surrounded. Alliance paladins retook Southshore in an attempt to purify the blight, while the Forsaken have enslaved the dwarf spirits at Dun Garok.

War in Kalimdor
Another major front, the conflicts in Kalimdor is mostly fought in the northernmost territories, with the Kaldorei lands seeing the majority of the fighting following the burning of Teldrassil by the Horde in 38 L.C. and the official beginning of the war.
The Kaldorei resistance waged a guerrilla war against the orcs in Ashenvale and Durotar, with the remnants of their army preparing for an assault on Orgrimmar itself. At Ashenvale, the Horde marches on Astranaar while the night elves’ dryad allies have destroyed the Warsong’s logging equipment. Darkshore became a region-wide battlefield following the burning of Teldrassil, with the Horde controlling the southern and northern parts of the zone and the Alliance controlling the center. Prior to being blighted by the Forsaken, the night elves used Lor'danel as a port to send refugees from Teldrassil to Azureymst Isle, which the Horde planned to launch an assault on from the Zoram’gar Docks. Bael Modan became the site of a battle between the tauren and the dwarves, who are preparing to invade Mulgore. A large Alliance army attacked the Crossroads, and the Steamwheedle Cartel pushed their neutrality to the limit by secretly aiding the Horde against the Alliance. Both factions are sending scouts to the ruins of Theramore, with plans to build a new base there.
