I came up with a semi-logical way for the gun to work. Black hole, boundless energy, contained by stuff I made up that can bind black holes. Does that not fall into the category of logical? As for the sky thing, sure, that COULD is why it is purple, but did I need to say that in the story? No, I just have to say it's purple, and let my readers imagine the reason. The sky COULD be purple because this world is surrounded by a big lady and her dress makes up the sky :P

The problem with putting very strict rules to any world involving magic, is in many cases, the rules governing magic, if indeed there are any, tend to run contrary to the rules of the rest of the universe. 

And no, I don't hate anybody, but in the case of this RP, there are certain things I need for the RP, and certain things that can not exist for me to enjoy myself. Like the robot mentality. I guess I have to drop this here: The RP is far from over with the fruition of Alexi's plan, and the rest of the world outside the house walls will be VERY relevant after the plan's climax. The story climax is waaaay after the plan. It's one of the reasons I've been so picky about tech. If certain things exist, the plan would either not work, or need some major additions and changes. 

In short, I don't wanna lat out this huge net of the tech history and current status because that would totally f'up(Most likely) not only the plan, but the rest of the RP after it. I'd rather not lay down something that makes sense to you and makes you comfortable, only tome come in later and say, "Oh, by the way, this tech can't exist otherwise this whole thing falls apart" and either have you not want to change, or have to re-work the entire grid.

Oh, and for Erik, what I just said above may help you with that. No matter when he gives in, there is a LOT more RP to happen after that 4th dose :P
