"Clang ,clang, clang went the trolley"

From out of the gloom bounded a pack of hell hounds, breathing fire upon the party members standing in the tunnel. The dragon shaman's protective aura made this ineffectual and soon the hounds were slain.

A little later, laughing and grinding could be heard further down the tunnel. Soon a huge trolley being pushed by a troll and ettin rolled into view. Unless stopped, the trolley would hit the party and cause massive damage.

The monk jumped onto the trolley and attacked the ettin. Immediately afterwards, Benedict the paladin stepped back and summoned a wall of ice across the tunnel. The trolley hit the wall and smashed part way through before coming to a very quick halt. The troll and ettin managed to brace themselves and keep their balance.

The samurai used dragon breath to get through the wall while the paladin hacked a hole instead. All passing through the access holes took freezing damage from being so close to the magically summoned wall.

Meanwhile the monk had stunned the fiendish ettin long enough for the rest of the party to take it down.

The troll couldn't regenerate the shaman's dragon breath or Squick's transfer of damage so was soon knocked to the floor by the paladin. The samurai then took ages to burnt the last bit of life from the giant. Clouds of pungent, acrid troll fumes filled the passageways.

Adriana summoned an arcane eye to explore the area. Above the tunnel she found a dormitory with six of the ten beds occupied with sleeping giants and an infirmary with two giants behind glass walls (one asleep, one shaking from side to side) and a raptoran chained to a perch.

Other rooms included a furnace room for melting glass, a large store room for raw materials and wood, and a smaller store room for supplies (food, equipment, etc). Behind a curtain in the last room was a statue of Surtur.

Two giants were awake and on guard at a barricade on the far side of the living area, watching the Underdark for threats.

Back in the tunnel system, a large stone chest was discovered set into an alcove at the junction of some passages.
