Descent into the Underdark

With a loud whoosh the entrance to the cavern is filled with flame and the spiders rushing at you begin to scatter. The cobwebs near the flames all shrivel instantly, exposing more of the caverns interior, but the smoke and flames make looking inside or getting near difficult. The combination of flames and webs quickly causes the oil tossed into the room earlier to also catch. The flames do not fill then entire cave and some of the spider form the cave flee it on the ceiling into your part of the cavern. . .

The are some loose rocks lying about and while some of you move to prepare to block up the passage you pause as you realize the spiders are no longer moving in a cohesive manner and are simply scattering from the flames. But the little fuel you have tossed in the cave will soon burn out. As you watch the flames, squashing or side stepping the occasional spider that wanders to close.

The spiders in your area are unorganized and react like normal spiders and flee your approach.

You manuver the barrel of oil as closs as possible before Isuzu uses his pole to push it forwards then into and through the flames. He uses his telekinetic powers to keep the thing from tipping early then knock it over. You all quickly retreat and after a moment a loud whoosh is heard and the flames grow in brightness and intensity.

By this point the flames have drivven the spiders deeper into their own cave or perhaps out into the open? Either way you have little to do for the next several minutes as the oil burns and the flames slowly dwindle to mere traces. Still the heat of the rocks makes you wait a bit longer before moving towards the cave.

The stench is terrible when you finally move to enter the side cavern. Though not wide or deep you ralize it is very tall. The light you saw from before is much brighter and far overhead. Most of the webs were destroyed by the fire but a few tattered remnants remain high above. The cavern floor and lower span has been burth clear of all webbin and not a single spider can be seen. The webs are too high up and the walls are smothed so the any attempt to climb will be difficult. You search the lower reaches of the cave and find nothing but a few chard spider corpses of various size. To solve this riddle you will need a way up . . .
