Scholar Josir is trying to woo the Marquise whenever he can. He talked  her into letting him and his order, the Durmand Priory, helping her rescuing the kidnapped children from the swamps. Fair enough the method they came up with worked out but the guy himself is so .. well .. boring.

Ihan of the Order of Whispers, on the other hand side, is all the opposite of boring. Ever since the Marquise first laid eyes on him she can barely think of anything else.
And now, take a look at this scene: It would have been so perfect - she was there, he was there, a cozy hammock was there - but apparently it was not enough. Ihan was rather interested by her other skills, incredible as it may seem.
Well - she'll show him how skilled she is and help him track the Seraph and fight along with him.

In order to make Ihan a bit jealous, she joined once again forces with the Durmand Priory to lure some information out of the ghost of Alastia Crow who admitted having corrupted Kellach the seraph - so this is why he believes he must kill Queen Jennah, since only her blood can purge the corruption in Kryta.

The Marquise would rather not put her money on the gods - she prefers to take action herself!
Jennah - "Her majesty Queen Jennah of Kryta" to you ! - is in great danger but don't despair, the Marquise will bring deSaster to everyone who dares threaten life and sanity of Kryta's regent. Logan Thackery of course will help.
This time the Marquise again chose Ihan and the Order of Whispers to be at her side.

And with this her final choice had to be taken. Admittedly it was not an unbiased one.
Josir and the Durmand Priory efficient enough but a bit boring with all their research and machinery.
Whatever the name and aim of the girl of the Vigil was - the Marquise does neither remember nor care. She does not want to meddle with belligerent bitches in heavy armor.
The Marquise did of course chose Ihan and the Order of Whispers!
