So as Isha flipped the table, it disintegrated into fey dust or something. We readied our weapons, and I quickly shot the collar off Tria's neck, hoping that would break the spell over her. Isha tried to lure her outside, and though she seemed more composed than before, something was still preventing her from leaving.
The fey cast a spell and suddenly there were several mirror images of her. So we didn't know who to grab. Rathimund, Isha, and I alternatively struck at the Fey when we could while trying to get Tria out of there. Eventually, the Fey fell to our blows, laughing all the while as if it were an amusing occurrence. But not before he changed our surroundings to a howling, desert sand storm. At some point during the chaos, Azralon appeared, and after Rathimund finally managed to get a hold of Tria by slugging her and knocking her out, Az ran off with her with undue haste.
Another fey had joined the melee, this one more serious and seemingly more dangerous than the previous one. The rest of us covered Az's escape, my arrows felling the hobgoblin guards who attacked us. Impossibly, while my arrows struck true against the goblinoids, my arrows were ineffective against the fey warrior. He must have had some special defense or something!
Eventually, we managed to run away, fleeing the wyld, and then meeting up with our guide and my men and taking refuge in a cave. Tria was back to normal and let us know what she saw in the letter- the Empress offered her hand in friendship, and asked the Satraps to remove the house ambassadors and their families and build up their armies. For their loyalty, she promised long life and power equivalent to that of the Antathema. And enticing offer to be sure, but it did sound like there was a glamer on the letter to make the offer much less refusable.
Since Tria's satrap was the only one that was having, issues with those orders, this was an opportunity to prevent it from falling under the Empress' control. Az proposed Tria depose her father, since she was heir. So we planned to return to the city with great fanfare, as surely her father would make no move against his daughter under the eyes of the entire city.
