When Ariel got her arm amputated by Kalki the last time she was here in Felde, Faen was right there with them when Snad used Floor Dragon to restrain Kalki. It's excusable if the barely conscious Ariel couldn't recall that, but kinda ironic (to put it mildly) that Faen, who was concerned with keeping Snadhya from touching Ariel, wouldn't remember Floor Dragon and let her own mother know that 'pssst hey Mom, Snads has summons'. Then again, I suppose Faen and Ash exchanged all of what, four sentences or so, in the story (not including Kite's adorable chibi page, which had as much if not more dialogue than mother and daughter shared in canon). And the most recent one was in the third person, at Machike. Still, that's kinda important intel that I'm sure Kel'noz would have gleaned from anyone who survived that misadventure, to make sure everyone going back into this dragon's den would be made aware of. I might have missed that exposition, in the intervening pages. If not, onus is on Kel for not passing that analysis along when announcing this mission...
Kel'noz: "Okay, our target for today is...FELDE."

Crowd: (gasps ensue, including one requisite spewing of a beverage being drunk)
Kel'noz: "Now, we know that Snadhya'rune may be there, but we're gonna go in there and mess them up! Any questions?"
An Inquisitive Fellow: "Uh sir, can you clarify what exactly our mission will involve?"
/Kel'noz: (irritated) "Weren't you listening? We're going into Felde and we're going to mess them up! Okay, let's go!"
An Inquisitive Fellow: "Uh, wait..." (gets drowned out by all the wolf howls, swept away by the Crowd)
I mean, didn't they notice the Floor Dragon t-shirts and plushies at the Felde gift shop? (insert facepalm emoji here)
