I apologise for responding to this, not being of Lord Thoth's order, but
I figured I'd put my history of my people to use.

The order members of Lord Thoth are known as Qui'anar because during the
war of the gods at Nishnatoba the Quisalis were a race of snakelike
beings loyal to Lord Thoth, (which assasins now have the honour of being
titled after.) They snuck into the camps of the Triumverate at night at
slew many rajamalan in the name of their Lord, only to be discovered by
unsleeping vampire guards of Slith. As vengeance, when the Qui'anar rode
into the fray the next day to face the undead hordes, Lord Thoth gave
them great power to assist them. Incidentally these Qui'anar later
became the Tsol'teth, perhaps corrupted by Pazazu's demon hordes, or a
mixture of that and Lord Thoth's blessings (as an unintentional side
effect, naturally.) So Lord Thoth's order members are named after the
Qui'anar in honour of those at Nishnatoba and their servitude to the
Lord of Death.

Here's the exact writings from the Mythos...
"That night, Thoth's serpentine Quisalis assassins crept across the
wastelands of Nishnatoba and performed their deadly trade upon the
forces of the Triumvirate. In a triumph of stealth and deception, the
massed forces of the Rajamala were murdered in their sleep.. This was
their greatest hour, for death was their pleasure and this was truly an
orgy of blood. However, sleepless vampire guards, set by Slith, detected
the Quisalis killers and, arousing the rest of the undead forces, began
to steal their life forces and turn the Quisalis into undead. The
Quisalis were wiped out that night and became martyrs; slain while
worshipping their beloved God of Death."

"Freed from the constraints of the magical barrier, the Elder Gods
rushed forth onto the battlefield. Proteus and Daedalus absented
themselves to search for Khalas, whose absence was suspicious and
disturbing. Aegis sent forth the war machines of the Arn mercenaries.
The Scrula and unicorns were turned upon the Nevaharr while the
Qui'anar, who had not participated in the previous day's battle, were
sent to fight the undead. Aiding the Qui'anar was Thoth himself, who was
overcome with rage and grief at the loss of his heroic assassins. He
drew on his own divine essence to amplify the lifeforce of the few
remaining Qui'anar, granting them near-eternal lifespans and powerful
resistance to the parasitic magics of the undead."

"So, the Qui'anar advanced upon the undead, the unicorns charged the
remaining Nevaharr and the Scrula and Horkval engaged the Aldar and
remaining Kx'Khrah. The mercenaries of Arn and the dwarves were held as
a harrying force and they circled behind the enemy to weaken their rear
flanks. Matsuhama and Vastar strode into battle to assist in countering
the Aldar. Matsuhama turned his anger towards Yen-Sorte, who he felt had
betrayed him. Though skilled beyond all mortals, even Yen-Sorte could
not stand against Matsuhama and soon fell. Vastar began hurling
lightning and meteors about him, wounding and killing many Aldar."

"Han-Silnar, seeing some of the most powerful Aldar being slain by Gods,
called upon Agatheis and Lorielan for assistance. Lorielan strode out to
meet Vastar in battle and the two were soon occupied in battle. Agatheis
sent out forces of earth and fire elementals to slay his enemies, but
Gaia was able to counter these with earthquakes and localized
rainstorms. The Qui'anar were slaughtering the undead forces and
banishing them to final rest. Prince Slith saw defeat at hand and the
rage-filled form of Thoth in the distance. He retreated with his forces
into the Ether, quitting the battlefield and preferring to try to
reconcile his differences with his father rather than face Thoth. The
dwarves and the mercenaries of Arn joined the diminishing Scrula against
the Nevaharr while Phaestus, the Smith picked up his newly-forged Hammer
and began laying waste to the Kx'Khrah."


I included extranneous information because... well reading is good for
you.

This history lesson brought to you by Cypra, and people with probably
too much time on their hands...
