You explore the Western passage, and it is choked with rubble and blocked by steep slopes. Moving up the slope requires 5 feet of extra movement. Alice can see that all the supposed prisoners are just more goblins but unarmed and smaller, they aren't wearing armor, and they're cowering. Although this passage is the only way, it's more dangerous than it looks, giant cracks descend deep into the earth, one slip or push could send someone down and quickly out of sight likely never to be seen again. Pebbles and small rocks tumble down as you pass and you don't hear them hit any bottom.
Yulya crawls on her belly searching for traps. [1d20+5=9]If there are any she can't be sure.
[1d4=3] Eyes shine back from one of the cracks, a large venomous snake coiled on the fragile ledge between the two escarpments peers toward the light. It slowly uncoils and raises its large head.It's a medium creature, big enough to eat goblins.After a loud hiss, two more slither out from cracks behind you.
Three goblins stand above you peering down toward the light and begin to cackle as they see the snakes slither out. They prepare their bows to rain arrows down on you.
