Mine No. 4

Mine No. 4 was one of the newer mines owned by Mining Co.. The party escorted a group from the company to go and survey the mine, however the trip did not go as planned.

Location
Mine No. 4 was located a few hours outside of Mining Co.'s headquarters. There were multiple routes to the mine, however the main one was out of service when the party visited. The alternative route led past a cave that was home to a group of goblins and a river that said goblins used as an ambush point.

About
Mine No. 4 was made up of a central shaft with a lift, along with branching tunnels dug across at least 5 layers, with deeper tunnels generally being newer. The central shaft contained a pool of water at the bottom and some of the branches leading from the centre were boarded up. The mine itself was described by Marcus as being one of the newer ones, but this did not necessarily mean much as his descriptions of the older mines made them seem very old.

The mine itself has suffered from multiple cave ins. Some of these were caused by a resident ooblex, however there were also trapped miners who had not witnessed any sign of the creature.

People
Bob: A foreman in the mine. The party had previously found his corpse in the goblins' cave along the road to the mine. The Bob they met inside the mine was a puppet created by the ooblex.

Marcus: On a trip into the mine to survey the area, Marcus became separated from Nemo and was killed by the ooblex. His body was later found in a pool of water in the caved in section. When the party thought they'd found him, he turned out to be a puppet created by the ooblex. This same puppet was also used during the fight in an attempt to demoralise the party.

Roger: An anxious guard who the party sent to get help when they discovered that something was very wrong at the mine. He met a group that were already on the way on his way to headquarters.

Igor and Johnson: Part of a group sent to rescue the party from the mine.

History
The path to Mine No. 4 becoming blocked by a broken bridge led to the need to use the alternative path to the mine in order to keep it running When scouts were sent by Mining Co. to make sure that path was safe, only one of the two returned, and even that one had discovered goblin activity in the area.

The party was given the job of clearing out the goblins and finding what remained of the missing scout. They found the scout, along with Bob's corpse in the cave the goblins were using as a hideout. After taking the scout back to Mining Co. headquarters for treatment, the party was tasked with escorting a group along the path to the mine. During this trip, they killed most of the remaining goblins and arrived safely at their destination. At this point, Nemo and Marcus entered the mine while the rest of the party and Roger examined the broken bridge.

When neither of the two came back, the party went to investigate and found Bob (actually the ooblex), who told them that everything was fine and the size of the mine was the reason that things were taking a while. The party believed this and went back outside for a while.

Eventually Ragmesz realised that Bob from the mine looked identical to the corpse from the cave. At this point, the party launched a rescue mission and sent Roger to get help. Upon entering the mine, they discovered that the lift had had its rope cut, so the party carefully descended using some rope and the feather fall spell.

They found Nemo in the second from the bottom layer and set out to find the ooblex. Along the way, they found Marcus trapped behind a caved in wall and went to go and get him. He turned out to actually be a puppet of the ooblex and trapped the party in the cave via multiple cave ins. After finding the real Marcus's body in the water and making some attempts at clearing the rubble, the party came face to face with the ooblex again, this time leading to a fight. The party eventually won after a long, hard fight but were still trapped. After more attempts at clearing their way out, the party was eventually rescued by a group sent by Mining Co. who had met Roger on the road.

Also in the mine, the rescuers discovered a group of trapped miners, who were also stuck in a separate cave in. They had not seen any sign of the ooblex.

The next day, everyone was sent back to Mining Co. headquarters.

Notes & Trivia

 * This map caused a lot of lighting / sight issues, because when does Roll20 not have issues?
 * The early part of the time in the mine was really just a parody of Pixar's Finding Nemo but with more rocks and less fish.
