Cedric and all of the others scoured around the cave looking for any way out that didn't involve going back because they were pretty sure even though they might be able to put up a fight that they would still lose.
Then Cedric went up to the dwarves and said "hey I thought of something you guys could use your pickaxes and we could dig our way out of here without going back." After we gather the necessary resources to support the tunnel then we can get out of here said one of the dwarves.
So the the entire group started to collect supplies to make supports for the tunnel. The spiders used there silk to pull the supplies to the side where the dwarves would be digging but since Skyra and Vyra won't be able to do a whole lot since they don't have the ability to pick anything up because they don't have arms and hands. They will guard the entrance just in case the spiders somehow break into the cave throughout the sealed entrance.
After half a day of spending there time collecting supplies for digging a tunnel the dwarves got to work. The dwarves dug while everyone else helped with the supports it was wide enough for the spiders to fit through but the didn't worry about Skyra and Vyra since they could fit through the tunnel.
About 8 hours of digging they break into a massive tunnel that was as wide as a football stadium. With side tunnels all over it. But their was some features that freaked everyone out except for the spiders and the snake duo. There was massive spider webs all over the tunnel some as big as a bus.
The elder dwarfs said in a soft voice and very quietly as not to disturb anything if none of the spiders had heard them digging. "It is said if you ever find one of their nests that you should never enter them because you wouldn't make it out alive. A army was sent by the humans to clear one we heard and not a soul came out."
freaked even more by this the dwarves and Cedric and everyone else quickly but carefully made their way through the net work and occasionally hiding from roaming guards. But someone tripped and fell into a web and the maze of tunnels sounded out with loud screeching. So they all rushed to escape and slowly being cornered they found a small exit that they could seal after they went through it.
So they went through it and just barely seal it in time.
