((I think this is a plan that involves everyone and minimizes risk. Feel free to tell me how horrible it is and suggest improvements/changes.))
Kara will try to gather Nyw, Drett, Clate, Vikkan, Adam and AsHul and explain to them her plan. Anyone else is welcome to join but those are the people Kara trusts and/or needs for this little mutiny.
"I have no reason to trust that our employees will simply let us go once we do our job. In fact, I believe they will most likely take us out the moment we're no longer a danger to the artifact and to them. And I'm sure most of you feel the same. So I propose we take the bore over. That's why I've gathered you here. So we can discuss a plan to do so."
"The plan I have hinges on certain things happening. If those things don't happen, then I want to state outright we're probably better off pretending we were never going to try anything and hope our abductors won't just kill us when we're done. I want to be clear that I DO NOT want us to die for some stupid suicidal plan or for honour or the church or anything like that. I want to maximize everyone's chances of survival, mine included."
"So, the plan. First, we can use Clate's rod to gather as many constructs as we can. They can be commanded to attack or act as cover. There's also a 'find' command, maybe we can use that to make them find and pick up weapons. Even if they're not very effective at combat, they will give the guards something other than us to shoot at."
"Once ready, we send Vikkan to the bore, along with anyone else who wants to join the group inside the bore. The bore group will disassemble the lift for later use and prepare traps and hiding places inside the bore if they can. Using his injury as an excuse, Vikkan will very slowly pilot the bore back to our original breach point, to give us time to prepare. If asked, he can say that we found the Artifact but can't risk bringing it up through the lift (we can say that it's held in a heavy construct we can't open), so we need to relocate the bore so we can use the bridge."
"Meanwhile, the rest of us will cross the bridge with the constructs and prepare a trap on the place the bore will be. Seeing as the Star Dragon is able to remain active a small distance away from the ruins, I'm hoping the other constructs will also be able to function. We hide the constructs and wait for the bore to arrive. Once the bore arrives, a team waits for some guards to get out. If they don't get out, we can send someone good with words inside to try to convince them to come out. Maybe we can say we want them to identify the Artifact before we risk breaking the construct that has it."
"The biggest threat to us is those collars. The most important part of the plan is we need a Diver to temporarily disable radio communications. I don't know much about diving but I think it would be easiest to shift radio frequencies or otherwise scramble them, rather than outright stop them. A tinker can also try to do the same using any antennas we have on the bore. Even if the effect doesn't last for a long time, hopefully after the first few failed attempts to detonate they'll stop trying or will be too busy to try."
"We should try to keep our attack quiet for as long as we can. We need to try to prevent them from retreating and regrouping or alerting the others. The more we can ambush the better. However, when we go loud, we should not hold back. Our lives are worth more than theirs. The only thing worth more than the life of one of us is the bore, since it's our only way out of here. Without it, we're all dead. We might be able to repair parts of it, but the control room is extremely fragile and complex, we can't afford any harm to come to it. That's why I propose Nyw accompany Vikkan in the cockpit (he can say he's just helping him climb the ladder). He's an Honored Dead, they're supposed to be the best at close range combat, so he's our best chance of taking them out without harming the control room. Once we go loud, Vikkan can move the bore around to cut off the control room from the rest of the bore. He can also shake the bore to disorient our enemy, giving a signal beforehand (e.g. rev the engine) to ensure we have time to secure ourselves."
"If the diving fails to disable the collars and surrender is not an option, then... I know it's desperate but I can try to hug one of the guards and... steal their detonator or punch them or something. Hopefully they'll be smart enough not to risk detonating the collars with me so close." And if they do detonate, it will be one less guard for the rest of us to worry about.
"When we are victorious, we can find a way to remove the collars or interrogate the guards for the location of the key we need to unlock them. If we're lucky they'll have it on them."
"There is an alternative to all that. We could have someone light the artifact on fire and pipe the fumes through the bore's ventilation system to knock the guards unconscious and maybe kill them, but there's too many things that can go wrong with that. It would be better if we had some airborne poison, but even then it would be risky and indiscriminate."
"For my part, I think it would be best if I use my rifle (and any rifles we pick up from the guards) to support the offensive. I'm also quick and a good climber, so I can act as a messenger, deliver supplies or find alternate routes and vantage points if Vikkan turns the bore around."
"So, uh, that's it, more or less. Any thoughts? Opinions? Suggestions? Should we vote on it or... is it terrible? I'd understand if you don't want to do it, I'm just as afraid as you are, probably more. But I prefer doing something about it than resigning to my fate. Fortune helps those who help themselves, after all."
