I did intend to make at least one more post before the actual timeskip, yes, and my idea was that Aemoten's group would just arrive and take care of their own immediate business for the time being, and - since people seem to prefer that idea - postpone the meeting of that and I'on's group until the next morning. There are some things that Aemoten's group will have to deal with, though (like the poor rune mage that has been standing by the gate all day waiting for them), before they can retire for the day and get some well-deserved rest.

EDIT: And Rhaevnn posted just before me. Concerning the treatment of Seclyrian sniffers, that usually depends on the circumstances of the sniffer's recruitment; a sniffer that was forcibly made one because its affinity for magic was discovered and not willingly surrendered would indeed be treated more akin to a prisoner than an ally, whereas someone who voluntarily submitted to being made a sniffer would be treated more like a comrade. If one isn't immediately aware of how one came to be a sniffer, however, Seclyrians are more likely than not to simply ignore one such and treat them as little more than part of the furnishing.  
Sniffers are also usually accompanied by a small group of soldiers in Seclyr, yes (actual soldiers, too, not just guardsmen) who act as the muscle once the sniffer detects a magical anomaly nearby. Sniffers are usually used in special anti-magic patrols and are deployed one per each of these squads, and they practically never get an opportunity to meet one another except when they are off-duty.
