... No way. If the council recognises individual wizards with their retainers as accord members every warlock under pressure is going to try that.
The White Council doesn't get a say: they are
subject to the Accords, not
in charge of them.
A
prospective Accord member just has to get a few
existing Accord members to sign/sponsor them. That's how Marcone got in. In the abstract, that's how rando-warlock could get in.
(Of course, the newly-Accorded party needs to demonstrate they CAN play in the Big Leagues... note how the Denarian's attacked Marcone, with the cover-story that they were removing a "presumptuous upstart" not really "entitled" to be Accorded; and without an Accorded protest, that action would evidently be allowed to stand! So if Rando-Warlocks tried to get Accorded -- and actually got the signatures -- then the WC could just "Nope" and arrest them anyhow; then see if anyone else wanted to protest, in that "Willing to paint a big sign on myself saying, PrimaryTargetOfWhiteCouncil" way... Maybe add a day of waiting before the execution?).
But the WAG here is
NOT Elaine getting recognized as an individual wizard (with retainers), but
the Paranet, the organization (with her at the head, admittedly) getting recognized. What the Paranet needs -- since they aren't ON the White Council -- is enough mojo to make a credible showing in their own right.
I'm WAG'ing that they CAN muster that mojo, as follows...
Elaine shows up as splashy and powerful, to be The Face, to make an impression. But there's a LOT of paranet'ers. The same way Ordo Lebes joined forces to raise wards that none of them could have solo'ed, Elaine's own magical-theorycraft & position (coordinating a
continentful of Paranet'ers!) could let her gather quite a bit of power into items and enchantments. A bit of Cassandra's-Tears precog in battle (so she knows what EVERY foe is most-likely to do, a second or two before they do it) and
many many more little bits of advantage. The ocean itself is made up of many many drops of water, after all; and Elaine's capacity to contain and inform and concentrate and
leverage those little bits of power could produce truly formidable results. She could probably get serious power-boosts for some lieutenant-y figures, too... imagine if all the Alpha's had a half-dozen Paranet-given battle-buff's, for example.
And maybe (or rather,
probably) Agent "I can magically tell when you are lying" Tilly as a Paranet member... and
his backup, the 70000+ Special Forces operatives the US military maintains; some of whom can -- in the leadup to the Peace Talks -- be given a Spooky Infodump & special training for Whamps, Blamps, Summer & Winter Courts, Wildfae & The Hunt, various were's and other shapeshifters, etc etc etc...
Masquerade bye-bye.
Kemmler would have been a member.
The de-facto WC position seems to have been that Kemmler
was a member -- they killed him for breaking WC laws. If Kemmler had been willing to abide by those laws, and showed up at Council meetings to be a voting member, they'd have been "yeah, sure, strong enough, of course you're on the WC."
They don't try to assert a death-penalty on every Whamp who does a psychic takeover of mortals, for example, because the WC's Laws don't apply to Whamps.
They don't invite minor talents to join the Council, because not strong enough; so Paranet talents aren't part of the WC, aren't Accorded.
The WC (Harry) chose to assert protection over them, but they aren't part of the Accords. The WC also chooses to visit/warn any group or individual they notice developing enough power to potentially break the Laws, and order them not to do that; but that's more akin to how Vamps order their mortal minions/food around. Justine cannot make
her own claim under the Accords; but she can present
Lara's claim.
It boils down to GETTING onto the Accords with the sponsoring member's signing you up; then STAYING there when a whole bunch of next-level powers start testing your new status -- there is no "spirit of the Accords" (except maybe a "Law of the Jungle" spirit).
So if Elaine makes a Paranet-based claim -- if she gets the signatures -- then the Paranet
is an Accorded party. Maybe the WC then says to her "hey, you're one of US!" At that point -- with a separate Accorded power-base -- she might not even protest that much (or she might deny them, pointing to their prior tests, and say it's the Paranet that gives her enough power). But she could be BOTH Paranet AND on the WC... then she's Accorded under both groups (as are, for example Vadderung / Kringle, or a certain WC-Warden & the Winter Knight, and I presume others).
... The council will claim her and she gets a grey cloack and no other members will complain so she better keeps her head low.
They need to
persuade everyone to go Greycloak, they can't
force them (because one unwilling battlemage in a group, who decided to go rogue to escape, could destroy the whole group by a strategically chosen moment to rebel). Harry wasn't happy to put it on, but in the end he
chose to.
As above, she can probably refuse the WC, under a separate Accorded status (but I suspect she would not, because WC membership would enhance her abuility to elevate the Paranet). But she WOULD likely refuse to Greycloak, because she cannot reasonably do her head-of-Paranet duties while being subject to Warden Command.
