I have a few groups right now. All of them are the same players, but they have a few different characters for different campaign styles. Right now we're running their retired Clone Trooper and former Republic Captain.
Rila was with the Naboo sector security before the reformation of the Grand Army of the Republic. She was ordered to command clones on Coruscant toward the end of the war and refused to lead troops she didn't know. She was arrested and ended up fleeing the planet before she could be executed. Afterward, her best friend took the post and ended up moving into the ISB. This friend lead a team that tracked down Rila's family in an attempt to find her. That family is now dead and the agent has spent 20 years hunting for Rila.
Double is coming to terms with an Empire that no longer wants him around and has been trying to find his way in the galaxy after a life dedicated entirely to combat. He's tracking down some old Republic officers who let a lot of his brothers die on Mygeeto rather than send in armored and air support. He also has to deal with the things he did during the war as part of the 501st. He was part of the attack on the Jedi Temple (See how their stories line up?) and responsible for the extermination of several species the Empire found troublesome. It's a lot to cope with especially when the only thing you've been taught you whole life is how to fight.
I could go on and on about these two and how their stories have worked alongside each other, but I'm going to focus on our last session instead and tell the story that was my favorite session to run in a long time.
The duo had agreed to help out an Imperial funded archeologist find something on a planet out on the edge of the Hyperspace tangle. My players had been to this planet before, but not these characters. They feared this planet for what was there. The archeologist needed to locate kyber crystals for Moff Dargon of the Corellian sector. In order to do this, he had a force sensitive girl (Felune) transferred into his custody by that ISB agent hunting Rila. They were there to save the girl and get her out alive. They made a deal that they would help the archeologist get the crystals (his previous expedition didn't go too well) and they would be allowed to "escape" with the Felune.
They land at the doors to a large temple built into the mountainside and the Imperials unload their digging equipment. Squads of Cave Troopers move into mountain to secure the perimeter, but slowly go silent one patrol at a time. My players are scared now because the last time they came to this planet they found a large group of apes that were guarding the kyber crystals (think Congo) and discovered it was once used as a mine by the ancient Sith Empire. I have other things planned for this trip though. One of these patrols stumbles out having been attacked. The other troopers run out to help them and take one of the injured men's helmets off. His eyes are totally black and he snaps to attention, ordering his quad to attack in a language that no one understands.
The party helps out in fighting back these possessed Cave Troopers. This is the reason the first expedition didn't go so well. They take charge of the situation and move into the temple with the archeologist, Felune, an old squad mate of the Rila's, and a squad of Cave Troopers. They walk for some time, spotting shadows in the dark corners and hearing whispers in familiar voices. At one point, Felune opens a door that doesn't appear on any scanners but is clearly visible to the group. Finally, they're surrounded by possessed troopers when we have to call it for the night, exactly where I had hoped.
We start up the next session exactly where we left off. Their squad was now pinned down in an impact crater and surrounded on all sides. They looked at me confused as to what I was saying, and I reminded them of their mission to reinforce a forward base that their forces had just captured from the Sith forces guarding this planet. It had only been a few days, but my players seemed to have forgotten everything about the game in that time. They fight off this ambush and make a break for the forward base across the muddy plain. The heavy gunner stopped once to grab the Lieutenant and call her by a name that wasn't hers but felt so familiar. It couldn't be right though, because she was a Lieutenant, not a Captain. The Trooper fired at the silver armored soldiers, dropping them as more squads appeared. He cleared their path when his final shot connected with the droid’s chest plate. It fell to the ground with the words "Roger Roger" echoing from it's vocal processor.
They made their way to the forward base. Once there, they met up with the Jedi who requested their assistance. She told them they would be accompanying her into the fortress of Lord Dreneth where they would kill the Sith and hopefully end the battle for this planet. They made their way out and up the hill toward the doorway to the temple. The thing Double remembered most about the fall of the Republic is how quiet it was. None of them spoke as they walked toward the temple steps and climbed with the orders to kill every Jedi inside. They weren't moving fast enough though, and the Cadet had to get her squad through the obstacle course in under five minutes or she'd never lead on the field. They made it up the hill and looked down at one last valley that they would need to cross before they made it to the door. They fought more Sith Empire troopers and Rila got to make the best throw of her life from the outfield as her company’s team slapped the Fondor security team with a third out and won their game. The ball slammed into the mitt of the third-baseman where the explosion sent the heavy repeating blaster tumbling down the hill, now unusable by the defending Sith troopers.
The enemies were defeated and a hole was now open to the temple, and lord Drenith. Felune grabbed the Leuitenant's arm and squeezed, she was scared, but wasn't sure why. Sorry, did I say Felune. I meant the Jedi, I'm not sure who Felune is. This Jedi looked Rila dead in the eyes and said "Whatever happens, we need to kill Drenith." But she couldn't be talking to Rila. Rila was an officer for the Republic, she fought for the military creation act, she fought for everything that become the Empire. Double did too. He served in the Empire for years after it's formation. Empire, of course! They were on the wrong side of this.
The commander checked his blaster pistol and aimed it at the door. A thin, blue light broke through the stone, slowly cutting it's way into the room. "Whatever comes through that door," he commanded to the assembled Sith troops, "protect Lord Drenith." Lord Drenith himself stood behind them, lightsaber drawn and humming. Protect Lord Drenith.
The door burst open and a Jedi charged into the room followed by soldiers of the Republic. Rila raised her weapon to fire, turned to face Drenith, and pulled the trigger.
Everyone dropped to their knees with an instant headache. An ancient, rotting body, preserved by unknown technology, burned slowly from the inside out where the blaster bolt had hit it's chest. Rila and Double picked themselves up and helped the others to their feet; the archeologist, Felune, and Rila's squad mate. The whispers were gone, the shadows had vanished, and they stood in the innermost chamber of the ancient temple with the burning remains of Lord Drenith.
Overall, this was one of my favorite sessions to run. My players went right along with it and started adding their own things into the shared hallucination. We got to pull all kinds of memories from each of them and mix it in with this story from the past. I would normally be worried about trying to do this kind of thing, but these players care about story above all else and didn't try to meta-game their way out of anything. The entire time I would talk to them "OOC" as we talked about how things made them feel and what made sense. Eventually, they realized this wasn't me talking to them, but the thoughts of Lord Drenith probing into their memories and trying to make sense of everything. It was an absolute blast to run. By far my favorite session in a long time and one of my wilder ideas. I'm happy I decided to go all out for it and not worry about the outcome.
