Jango pulls out the bullseye lantern he picked up above and lights it up. The cone of light it throws illuminates the tunnel completely, and as the group looks ahead, they see it turning off to the left. The group lines itself up, and Skarghash and Taviss begin moving out in front. Ari, Khalia and Jango follow slightly behind.
The pathway down here is fairly easy to traverse, and both the watchman and the ranger are able to pick up and follow the evidence of a pirate trail. No tracks of course are imbeded in the stone floor... but the scrapes and scratches of weapons and objects against the stone floor and walls, plus various pieces of garbage dropped along the way. Having walked this tunnel countless times over probably several weeks had made the pirates very blase about keeping things neat down here.
The group walks for probably about five minutes or so. The tunnel turns and swerves several times... and there's never been a straightaway long enough that Jango's lantern was not able to enlighten. With a 60' throw plus an extra 60' of shadowy path ahead... the group has always been in the light. As you all walk, you occasional stop to listen for any sounds, but nothing reaches your ears. You also take stock on occasion of the direction you all are heading, and Taviss is able to tell that you are heading more towards the south. Khalia is able to deduce that this means you are pretty likely to NOT be heading towards the Xothkazzik Ruins (which would probably be several miles to the west at least).
Finally, the tunnel reaches a point where something different occurs. It splits. The tunnel continues forward ahead, but there is also a shaft that heads off to the left. Glancing down both directions, it is pretty easy to determine that most traffic has headed down the left passage rather than straight ahead. And when on an impulse Jango closes the shutter on the lantern... the group sees that the left passage is very dimly illuminated from some vague light much further along.
