Blackscale Lizard Lair

Upon entering the Upper Northern Passage, you realize that something is very, very wrong.
The walls of the passage have gone from being clean & well maintained, to gradually more dingy, grimy, scratched & occasionally smeared with blood.
The air smells vaguely of rotting flesh, & the ground crunches underfoot with broken bones.
The walls become slick with moss where water weeps from porous veins that leech up from an underground aquifier.
The ground turns slightly spongy, mossy, & covered in rotten vegetation, bits of animal flesh & bones, & offal.

[If they make a Search/Spot/Listen check before reaching the final corner, they have a chance of escaping back the way they came.]

Otherwise, BSL Scouts have spotted them & already warned the Community.
If so, they are met at the Entrance by 1d60 BSL Warriors.
Tall, bipedal-walking Komodo-like Dragons with light-to-dark grey scales, dim red eyes, & lizard like frill.
They're wearing leather loin cloths, simple harness' sheathing various knives & tools, & a rather vicious look in their eyes.
They aren't glad to see you, but they aren't aggressive against you yet, either.

[Percentage to determine state: 0-69 want to eat you / 70-80 neutral / 90-00 friendly]

They escort you to the "Main Court" where the rest of the Tribe is waiting.
As you pass a set of alcoves, you notice that some have small clusters of the BSL's.
// Each alcove is a sleeping area for a "Clutch" [1d6 Warriors, plus 1d10 Females & Kits] //
Others have larger clusters with more aggressively stanced BSL's watching your every move.
// Some of the bigger alcoves are the sleeping spaces for a "Pack" [1 hero, 1d10 Warriors, plus 1d20 Females & kits] //

The rest of the Tribe waits as you approach, whispering between themselves & filling the air with a raspy hiss.

[There's 100 minus how ever many met at the Entrance, plus 1d10 Tribal heroes.]

The Heroes are slightly bigger, taller, stronger, & faster.
They have more ornate bits about their loin clothes & harness, but otherwise indistinct from the others. 
(They ALL look lethal & in a bad mood - the air fills with a soft, angry hiss like a million angry snakes.)

One of the Heroes finally debases himself enough to talk to you.

[They all speak Common, but it is an insult among their people to actually USE it for anything other than curses.]

They want to know what you think you're doing invading their home, and a VERY good reason NOT to eat you.
