Aight, I finally got some time to read all this then.
..

I see if stein was broadcasting into Mithias's mind somehow but isn't anymore then Martin can't find it.
And if you shut down BIOpilot, or at least the parts that held backdoors for Martin (and sure, the programmer should be able to find them if h suspected they'd be there) then Martin won't be able to find BIOPilot.

I'm going to read the OC soon, first dinner. But quickly I'd like to point out that yes, being able to oneshot any NPC is pretty powerful, but every character in the setting can do that. It's a very high powered campaign and Stein has a warship along with free use of any technology that might be invented in the next 20 or so years.
SO excuse me if I use the psionic skill tree to it's full potential.
The redeeming thing that keeps Martin in check is that he won't murder anyone. And he isn't cocky btw, I might be, but Martin is just taking logical steps. He honestly believes he is immortal though, and in his current form, he's right.

I'm thinking of changing Martin's future plans, maybe something that will change his position in the story a little. Cause right now his only motivations are preventing Mithias from rushing towards death.

dinner first though.
