Wouldn't it have made sense then for the Kirin Tor to order the Silver Covenant to stop opposing the Sunreavers in Dalaran ?
If there is a source stating that the Silver Covenant serves the Kirin Tor I would love to have a link to it because I haven't been able to find it ?
Looking at their reputation description the Silver Covenant is: "A militant core of high elves that rejects the admission of blood elves into the Kirin Tor. They've united under the banner of Vereesa Windrunner and joined the Alliance forces in Northrend."
Why would the Silver Covenant join the Alliance if they served the neutral Kirin Tor and why would the Kirin Tor allow this ?
Tides of War explicitly mentions Vereesa had no "formal voice" in the Kirin Tor, which implies there was no formal relationship between Vereesa as leader of the Silver Covenant and the Kirin Tor.
In Northrend they were a part of the Alliance Vanguard: "The combined forces of the Alliance in Northrend, lead by the Valiance Expedition, but also including civilian groups such as the Explorer's League.".
Blizzard Insider #28 also clearly lists them as a faction or sub-faction of the Alliance:
"The Alliance and Horde have each mobilized their forces to fight the mounting threat of the Scourge.
...
Here is a list of the Alliance and Horde factions and sub-factions that have joined the front line in Northrend:
...
* The Silver Covenant – This group of high elves represents the Alliance in Dalaran, the floating city hovering above Crystalsong Forest in Northrend. The Silver Covenant opposes the entry of the blood elves into the Kirin Tor, the council of elite magi that rules Dalaran.
"
Blizzard Insider states explicitly that the Silver Covenant is a faction or subfaction of the Alliance and makes no mention of them serving the Kirin Tor.
The Alliance players also assisted Jaina, but that didn't mean the players serve the Kirin Tor or are under Dalaran command.
The Silver Covenant were founded to oppose the Sunreavers and that was no secret. It makes sense Jaina would ask her friend Vereesa and the Silver Covenant to help her.
Again could you please link a reference backing up the claim that the Silver Covenant officially served the Kirin Tor ?
To me it seems the Kirin Tor and Silver Covenant were simply allies fighting together for a common cause. In WW2 the French, British, Canadians, Polish forces fought together under USA command in Europe but that didn't mean they served the United States of America.
In the first Battle of the Broken shore the Silver Covenant also didn't join the Kirin Tor led by Jaina which indicates they don't necessarily always fight together.
Again could you please link the reference backing up the claim that the Silver Covenant officially served the Kirin Tor. I don't see how the Silver Covenant can serve both the neutral Kirin Tor and the non-neutral Alliance at the same time so if there is any lore source or Blizzard statement supporting this it would be interesting to read.
Which is why I'm seriously curious what reference you have found that the Silver Covenant serves the Kirin Tor because all the information I have found so far indicates they were and are a faction or sub-faction of the Alliance.
I read your interpretation of events but the Silver Covenant official description and Blizzard Insider #28 state the Silver Covenant is part of the Alliance, not the Kirin Tor so it would be useful if you could list the lore references or official Blizzard statements backing up your observations.
Blizzard Insider #28 (which is an official Blizzard source) literally stated they were an Alliance faction or sub-faction.
It was founded in Dalaran, but I don't see how that results in Dalaran having any control over it or owning it.
If the Silver Covenant left the Alliance with Dalaran in Legion then why didn't we see them controlling the Silver Enclave in Legion? Only a few rangers and mages staying behind, when most rangers joined the Unseen Path, would have been enough to to teleport Horde players away and protect their home instead of letting a bunch of Worgen rename it and leave hairs everywhere.
The Silver Covenant was part of the Alliance Forces in Northrend (according to their description) when Dalaran was neutral and A Royal Audience seems to indicate that the Silver Covenant, represented by their leader, Vereesa Windrunner, was still affiliated with the Alliance in Legion when Dalaran was again neutral.
