The crossbowman doesn't reply to Garrin's persistent knocking.

Keashirryl, you take careful stock of the room.  This room appears to be a large storage cellar, exactly the sort of thing one might expect to find beneath an old manor. The Redbrands must have wanted to keep their base of operations hidden, so other than the barrels filled with fresh provisions, nothing in this room gives away their presence.  The barrels contain salted pork and beef, flour, sugar, apples, and ale. Moving barrels around to thoroughly search them doesn't reveal anything unusual.

The cistern is another matter.  This rectangular reservoir is clean and filled with cold, fresh water. It is 10 feet deep with a rim 2 feet higher than the surrounding floor (so that the bottom of the cistern is 8 feet below the floor). Drain pipes the must lead from the roof of the old manor above fill the cistern with water.  You spot a rope hanging down from the inside of the rim. Pulling it up reveals a water-proof satchel hidden inside the cistern.  This satchel includes 50gp and a set of ordinary travel clothing.  It also holds two potions.  One, you recognize as a potion of healing.  The other is more exotic.  It appears to be an empty bottle, but it feels as though there is liquid sloshing around inside.

The other secret door is still ajar where the fleeing Redbrand pushed it open.  It leads into a wide hallway decorated with marble pillars.  There is no immediate sign of the Redbrand and he doesn't seem to be returning with help as he promised his allies.

The last door, to the east, leads to a staircase up to the ruins of the old manor above.

Sensing the hesitation from his new "friend", Droknin tries to break the ice. "What about I start the conversation?" Says Droknin extending his paw. "Name's is Droknin. We are kind of new in town, you see. What about you give us an overview of your lovely place here? You may want to start with where your friend may have gone. The one that left the party earlier. I promise that once we are satisfied with your tour, you are free to just go. We only ask that once you do leave this place, that you go far away from here." He emphasizes the last two parts so the person behind the locked door is able to hear him.

The man looks utterly terrified of Droknin.  

"Y... You're that cat-man what attacked the captain yesterday and then killed Slobomir.  They... They said you and your army might try to attack us here.  They called us of us in from the Sleeping Giant Tavern to guard the place.  We... we were supposed to spring a trap if 'n when you came down the stairs."  He looks back at the secret door you all attacked from, and then at his dead comrades on the ground.  "Aw geez... aw man... you'll get no more fight out of me, I swear.  They don't pay me enough for this."

"Reggie, that yellow skink.  He's the guy what ran off.  Down that way is the... the cell block.  They hold the prisoners there until Glasstaff sends them away."

He shuffles his feet nervously, awaiting other questions.

"If you were to ambush us coming down the stairs, what else is further on from here? One doesn't put an ambush after what they are trying to protect.",  T'laren inquires, arrow still half drawn.

"Um... well... like I said, prisoners are down that hallway, " he points toward where the other Redbrand ran off, to the north.  "Oh!  Oh, and watch out.  There is a big pit trap in the middle of that hallway.  It's safe near the edges but you will open the pit up if you try to walk down the middle of the hall."  He smiles broadly, glad that he remembered to warn you.

"And then back that way," he points toward the door you came in, "leads to the main barracks, the mess, and Lord Glasstaff's private quarters."

"Which leads to which back there?"

Cassius lowers his weapon now that they are out of combat, moving to clean his wound a bit while looking to where the crossbowman has barricaded himself. "Should we drag him out of there before he decides to come back later on."

The fighter seems to panic for a moment, not quite understanding what T'laren was asking him.  "Just the one passage... right across the bridge.  It goes past the bunk room, then to the mess.  Beyond that is Glasstaff's private area.  I don't know about any other passages.  I've never been further than the mess, myself."

T'laren nods. "Droknin, decide what you're doing with your... friend. We can't stand around here and wait for them all to crash in on us, if we can't get any of those other doors open, back to the caves and onward?"

((Would an overall map be possible, or at least an indication of what's where based on this guy's info?))

Droknin steps back from the Redbrand. "If no one else has any questions, or objections, I supposed my friend here is free to go." He looks at the Redbrand. "Remember that you should go somewhere far away from here."

"And if you see fit to warn your former colleagues to our presence, you'd better pray that one of my arrows finds you before my feline friend does. If you gave your word to him, you best mean it, and you best keep it."

Garrin will give this red brand the stink eye and mutter to Droknir "We shoulda' killed him for that. He didn't even surrender properly."

The Redbrand takes off his ruddy cloak and drops it on the floor.  "No problem there.  You won't see me again."  He flees up the steps toward the manor house above.

((Thanks! So the guy who fled is north of the fountain, heading straight across the bridge, the bunk room should be through the door to the south (should the guy be trustworthy), with the mess and boss's quarters to the north of them. The creature we interacted with fled north along the chasm, though the one in the middle to the north (or the one to the west?).))

[Yup Yup Yup]

Keashirryl, finishing inspecting the room, joins the others talking to the Redbrand. She hands the weird potion bottle to Garrin. "You might want to take a look at this."

To Kemp, she answers: "I don't mind if he stays. No quick way of getting him out comes to mind, and T'laren is right. Better keep moving." 

Then, she takes the cloak the last fleeing man just dropped and fastens it above her armour. It is not an elaborate disguise, but it may confuse some people in the battle for a moment, she muses.

"I am not against heading towards the caverns. It depends on what our priorities are," she says, pulling her braid from under the cloak and adjusting some folds around her neck. "Are you eager to meet Glasstaff first, or rather try to get the prisoners out of the way - set them free, I mean? I don't want them to run into the aberration, though; he probably isn't in a jolly mood. And if I were a wizard with questionable morals, I would keep any keys on my person. " 

Cassius gives a half hearted shrug before he moves towards the area beyond the room, gripping his staff tightly. "True enough. I think before we do anything else that perhaps we should free any being held captive in this place. Who knows what has been done to them."

Garrin will sip the potion, attempting to discern its properties as well as quality. A crappy healing potion tastes crappy, he's sure of it. 

"Rescue the prisoners it is then." Droknin starts to head towards the door where the other Redbrand left the party early.

Droknin leads the way out the northern secret door.

Thick dust covers the flagstones of this somber hallway. The walls are decorated with faux columns every ten feet, and the double doors at the west end of the hall are sheathed in copper plate, now green with age. A relief carving of a mournful angel graces the doors.

Now that the Redbrand warned you about the pit trap, you notice that all the footprints in the dust of this hall skirt closely to the walls and avoid the middle of the hallway.  Following these paths, you are able to avoid the trap.  

The copper plated doors push open with ease and close again on well-designed hinges.  This next room looks to be a burial chamber for the old Tresendar estate.  Three large stone sarcophagi stand within this dusty crypt, and propped up against each sarcophagus is a human skeleton clad in bits of rusty mail. False columns along the walls are carved in the image of spreading oak trees. In addition to the large double doors you came in through, there are single doors leading to the north and to the northeast.
