As you begin to move down the corridor, Daerryl notices tracks in the dust here. Some tracks were made by rats and some by humanoids. Make a survival check.

Looking down the corridor you see a section of hallway containing six doors, all slightly ajar. The area smells musky.

"Where are the goblins?" Raadox asks Meepo in the common tongue.  He puts his hands on the pommels of his two swords, beginning to get nervous and sends his magic-sight out into the area ahead, whilst listening carefully.

Perception (+2): 17

"Meepo has never been this far into Goblin territory. I think they are to the left. I just want to find our dragon again."

Raadox, you see the tracks and the humanoid ones look similar to the ones you saw previously and are human sized. 

"So Meepo, you are saying we are already in goblin territory. Well thank you for warning us of this. If you don´t have any more useful information, which I honestly highly doubt, you should go back to your bed and have a well deserved rest and we will have your dragon back in a jiffy." Selene then turns to the others and continues "So gentlemen, should we perhaps take the door to the left and complete our dragon rescue quest before investigating other areas of the citadel? If so, could you perhaps listen for goblin chatter by that door Daerryl?" Selene says pointing  a slender finger at the door to area 25.

Any magical emanations, DM?

 Daerryl kneels in the dust to examine the tracks before looking around at the walls and ceiling.

Daerryl you notice that the rat footprints are very recent but the human ones are older. There are two sets of the humanoid footprints, one set of four going in, and a more recent but still old set of footprints coming out, only there are 3 sets instead of four. 

No magic in the area

Meepo shakes his head, "Meepo must find dragon for clan. We are in the back area of goblins. They don't come this way. Always raid through other route." 

"Oh my brave brave Meepo, so we will have the pleasure of your company during this whole quest then. So while we are waiting for the others to look through the very interesting dust of this place, is there anything you have forgotten to tell us, like what is down that corridor or what´s behind that door. Since the goblins have attacked your clan, you might also have some inclination on their numbers and if there are any spellcasters among them."

"Um... I think there may have been a shaman but I haven't seen or heard any fireballs going off. There is a pretty sizable colony down there. There is a reason we haven't been able to fully recapture the citadel for the glory of dragons. Down deeper in the citadel is the outcast, who gives fruit and gifts to the goblins. Other adventurers went to fight the goblins a while ago. None of them came back. But you look stronger. You can beat them. You must.... poor Calcryx must be so scared with them."

"Yes let´s hope we fare better against that sizeable colony of goblins with their shaman backing them up than those adventurers, who my friend Daerryl is supposed to rescue wouldn´t you know. Is there still a possibility that your brethren can create a distraction by the other route, so we perhaps don´t have to face the entire colony of goblins to get to your beloved Calcryx?"

“I’m not sure they need rescued. It looks like they might’ve sent more goblins packing. There must be quite a few goblins down here, I recommend caution.”

As you begin doing down the hall, you hear skittering as three giant rats slink out of cells.
