Setting: 50 years after events of Wrath of the Lich King/semi-alternate timeline
(This is my first one so I thought maybe I should start with setting)
Timeline:
Year 34—The Lich King was defeated at Icecorwn by the joint forces of Alliance, Horde, Knights of the Ebon Blade, and Argent Crusade. Former Scourge territories, including Eastern and Western Plagueland, were divided into occupation zones.
Year 35—The peace-keeping organization, League of States, was formed with Alliance, Horde, and independent factions' representatives.
Year 36—Scarlet Onslaught, under the leadership of High General Abbendis, rebelled against Forsaken occupation forces. Marking the beginning of "Scarlet Rebellion." However, it was quelled in two months due to the intervention from the LoS.
Year 36—Scarlet Crusader in Alliance-occupied Eastern and Western Plagueland rebelled against the occupational forces, recapturing Hearthglen and Tyr's Hand
Year 38—Alliance forces under the command of Fordragon fought a decisive battle at Andorhal, effectively eliminating Scarlet forces. The reminding Scarlet Crusaders unconditionally surrendered. Marking the end of the Scarlet Rebellion.
Year 41—Gnomes recaptured Gnomeregan
Year 42—Dalaran and the rebuilt Stromgarde rejoined the Alliance.
Year 45—Alliance settlements in Silverpine Forest were raided and destroyed by Horde forces, effectively elimination Alliance presence in Silverpine. The LoS issued a condemnation but could not do anything.
Year 48—A group of militant high elves took over the ruins of Silvermoon under the support of the Alliance. This event triggered the Fourth War, an all out conflict between Alliance and Horde. The same year, Knights of Ebon Blade was disbanded and Argent Crusade joined the Alliance.
Year 56—The war ended with Alliance as victor; the Horde officially dissolved
Year 58—Due to lack of enemy, Alliance dissolved
Year 63—Groups of the Eastern Kingdom including Blood elves, Forsaken, Human, and Dwarf formed the Eastern Kingdoms Union (EKU)
Year 67—Orc revolutionary Guerava Axebreaker started the Orgrimmar Revolution with support from former members of Horde and even some members of former Alliance. He successfully re-militarize the Orcish state and created the Union of Sovereign States (USS).
Year 75—Large scale insurrections following the ideals of Orgrimmar Revolution occurred within towns and city of EKU
Year 80—EKU had been unable to quell the rebellion. Stormwind was the only member state that wasn't affected as heavily as other members
Year 84(the year this story begins)—EKU's ally, the night elves, attacked their break-away province of Eastern Ashenvale, which is under the control of pro USS night elves. Warchief Axebreaker of USS sent troops into Ashenvale to intervene and occupied the entire region of Ashenvale. Again, the LoS could not do anything except a mild condemnation.
