Well, let’s see.
Back in Vanilla and BC Weeven was a nameless mercenary, one of hundreds of adventurers who would end up roped into thwarting elemental lords, doomsday cults, scheming black dragons and necromancers out of their own volition. Then the likes of Khadgar and A’ dal began to take notice and call upon her specifically to go against established threats like Illidan or Kael’thas.
From Wrath of the Lich King onward the story made clear that Weeven was recognized as an exceptional hero of her faction for her previous exploits, a self-reliant adventurer fit to skip recruitment lines and get directly assigned critical missions as soon as she set foot upon the rocks of Northrend. Characters like Brann and Tirion began to call on Weeven directly to solve problems and adventure alongside them, discovering the eons old legacies of the Titans and culminating in witnessing the very fall of the Lich King atop Icecrown.
Cataclysm and Mists of Pandaria only went further on the Hero angle, getting Weeven acquainted on a first name basis with pretty much every faction leader, be it races or organizations like the red dragonflight or the Kirin Tor. Weeven was also one of a select few Horde agents in Pandaria for months before the Horde main fleet arrived for the second half of the story, and then a key player in overthrowing Garrosh Hellscream.
Then came Warlords of Draenor and actual recognition within the Horde military hierarchy proper: Weeven was officially designated as one of the Horde expedition’s commanders in Draenor. She was granted command over the Frostwall garrison in Frostfire Ridge, one of the two principal strongholds on the alien world alongside Warspear in Ashran. She also commanded troops and a host of her own named agents and enforcers, some of them capable enough to complete their own missions or even adventure alongside her in their own right.
Finally, Legion and Battle for Azeroth cemented Weeven’s place as the Champion of the Horde; on one hand, Weeven was recognized as the most capable adept of her class, uncovering legendary relics and once again leading troops and companions who willfully carried her commands. On the other, she accompanied established figures like Khadgar, Magni, Velen and Illidan at every turn to end a cosmos spanning, endless legion of demons. During the Battle for Azeroth, beyond her official duty as Speaker for the Horde in Zandalar, she became the Horde’s hero killer, disrupting Alliance efforts at every opportunity while being the foremost operative in advancing Sylvanas Windrunner’s plans. She battled and sent running both Gelbin Mekkatorque and Jaina Proudmoore in the process. She was also, once again, granted command of a host of troops and operatives of her own to send on missions of her choosing.
In short, by Shadowlands, within her own faction and the world at large, Weeven should be a big deal: she’s not just a capable, self sufficient adventurer who routinely pillages and weilds legendary artifacts to slay long established threats; she’s also an actual, official, recognized commander of the Horde military. One any Alliance character with a name should actually think twice about going against.
Alas, it seems as far as deciding anything along the other leaders goes… Weeven is granted the rank of Master, but she does not seat on this council…
