There's no need to climb up the side of the ravine to get out, as the path you used before is still there and usable.  The chasm isn't terribly wide, maybe 15 feet.  Are you planning on checking out the Spire, returning to Red Larch, or checking out one of the other keeps?

(Definitely staying here on the spire. How tall are the walls surrounding the spire?)

As the party lines up epicly to survey the obstacle in front of them, Kethra groggily joins the lineup, dressed like a little cultist, yawning and tired like someone who hasn't quite got all her hit dice back yet.

"I... Did you not--"Xanranzan started to say, but cut himself off mid-speech and gave a sly grin. "Ah, I get'cha now. This is one of'em matty jokes, yea?"  He chuckled a bit. "Aight, aight. I feel ya, man. I feel ya. Not sure if this is the right time for that sorta thing, but either way, the plan ain't really all that changed by much. Probably gonna wanna double time just in case we're closer to sun up then we think, so let's hop to it." Xan breaks off into a jog in his new disguise, far more eager than ever before in wanting to reach the tower and put an end to some trouble makers.

Alistair notices several windows he could use.  To be clear, the spire is a tower—not an object with walls around it.  He can see several figures moving around, all wearing the same design of armor and fitting the description of a Feathergale Knight.  He doesn't personally recognize anyone, however.

Rubin is out in the darkness, staying ahead of the group until they reach the spire itself, then he will fade off to one side, watching and waiting, ready to step in if things go badly. (What options does he have for options to get inside himself, if the others are allowed inside? I am guessing there will be torches around the gate, so that won't work for him.)

"I mean, well, I'd halfway hope they were after all that interrogating. Otherwise, I was gonna..." Xanranzan kept jogging up and eventually towards the spire but paused in speech there for a good minute or so. "Well, I dunno what I was gonna do! Otha then maybe question if my magic was actually working like it should'a before." He comments on with a bit of mirth to his voice.  "Remember we gotta play it cool when we're close enough. And, uh... maybe figure out a way to darken up things so that Rubin can slip in right behind us 'n all that."

"Great idea, you better get started!"

Kethra gives Xanranzan a little push, putting him up front.

"Tell 'em we just ran into some guard and have *urgent* business so tell them to put out the torches because we can't afford to be seen in uniform entering Feathergale Spire."

Working one of her javelins out with her blade, Kethra weakens it so that she could easily snap it in two with her bare hands, giving Xanranzan the help action on charisma checks on hurrying the guards along and skipping proper procedure.

As you approach the entrance of the tower, a voice hails you from inside.

"State your business!  Who's there?"

Xanranzan mutters a quick "You can do this" under his breath, before clearing his throating and slowing down to march with more a purpose than hurry closer to the entrance up until the dim portions of any outer lights of the tower if at all possible. "Who do you think you puffed up dust devil!? I am here on behalf of the Howling Hatred with urgent news." He states harshly and did his level best to keep his usual twang out of his voice. "And dim those lights. We have reason to believe you've had watchers on this place and cannot be seen entering it. So be quick about it and open the bloody doors. There's no time to stand on rituals, least you wish to find yourself at the bottom of the gorge at the end of all this."

Xan the Man's Intimidation: 27.
(Advantage roll being from Kethra's assistance.)

Robin smirks to himself, out in the darkness. He watches the gates and any potential arrow slits, looking for movement.

"Er . . .yes . . .sir?  But it's not really bright here, and the only way I could dim the lights is to put out all the torches."

The voice sounds incredibly confused, but doesn't seem to want to question you enough to actually stop you.  He opens the gate.

"Bara-ah-hambug! Just put out most of those closest to the entryway ya.. ya.. Ya Numbnut Nimbus! Hurry now! I don't got all eve." He demands. But just in case he might be pushing things a bit too far after that point, he motions for the others to follow as marched on and through the gates with his chest puffed out, hands folded behind his back, and just generally projecting an air of confidence.

What was to follow once inside would depend on what he sees from there. 

Rubin would slip up to stride in with the others. If the lights are not out, then he would become visible as he enters the lightened area, but then disappear as soon as he can find a dark area again. If no dark areas inside, then he would be frustrated but stay with the others in that case.

With a smile, Kethra would grab a javelin from a guard a bit roughly to replace the one she broke if they have one, but also using this to show her strength.

Quote from Brian_Avery >>

Once the guard let's them in, if he hasn't already doused the torches, Tyde will do so while saying, "No need to waste these as there probably won't be any more visitors at this late hour."

Then following Tyde's lead, she'd grab a torch in each hand, start walking the now open drawbridge and lets it casually roll off her hands and down the chasm below.

"You've already been told twice, don't let there be a third time."

With a sharp tone, the white haired girl hints that she is perfectly willing to throw more torches down the gorge, making them run them out of usable torches if the guards aren't willing to put them out themselves.
