… and if this info is right… Blizzard really needs to hire someone to keep track of their time…
Sironas a Eredar who sided with the burning legion and became a man’ari Eredar… at some point during the Draenei’s time on Draenor… Somehow worked with Kael’thas and blood elves when they didn’t set foot on Draenor yet… and somehow snuck those non-exist Blood Elves onto the Exodar and caused it to crash into Azuremyst Isle… decades later…
So… Kael’thas was somehow fighting a war against the Draenei… before the Dark Portal was even opened for this first time… WoW Lore was confusing from the beginning wasn’t it…
Blood Elves tussled with Draenei on Outland for control of Tempest Keep as a power source
Sironas assists Kael’thas with his fight with the Draenei, specifically those trying to board the Exodar
The Exodar is a satellite ship akin to the Mechanar, Botanica, and Arcatraz, which is all part of the overall ship structure called Tempest Keep
It is because of Kael’thas’ attack on the Draenei aboard the Exodar that the Exodar even fled, with Sironas and other hostile Blood Elves aboard
Because the battle goes in Velen’s favor, Sironas and the Blood Elves sabotage the Exodar, causing it to rip apart and crash land where it does in Azuremyst Isle.
There’s nothing out of order. Blood Elves were on Outland thanks to the opening of the portal and Illidan fleeing there with his Naga and Blood Elf allies after his failed attempt to kill Arthas. Once there, Illidan’s forces began subjugating Outland as much as possible, with Illidan taking over Black Temple, Kael’thas conquering Tempest Keep, and Lady Vashj creating a massive facility in Zangarmarsh to bleed it dry. The Draenei on Azeroth didn’t get there until after KT’s attacks.
