So, hey, that was definitely an interesting read. I'll get the nitpicky stuff out of the way first, then get to the good parts.
First, this really jumped out at me: when someone is talking, it's rather jarring if they have parenthetical statements in their speech. I noticed this when Albrin was talking about the races he had joined up with. If you replace the parentheses with dashes, it looks much more natural and the same effect is achieved.
Second, when you have a conversation that lasts a while, I noticed that you tend to drop identifiers (ie, "Rudolf said"). While it's not necessary in every sentence, when you have long conversations, it's good to tag sentences every once in a while just to keep things from getting confusing.
That's pretty much what stood out as far as things that need criticism. On to the pros:
I dig the characterization. Rudolf started out as just a headstrong kid, but by the end of the story, he had a whole 'corrupt with power' vibe going on. That happened gradually enough that I almost wasn't aware it was happening at all, and that's pretty impressive.
Even though a lot of the story was just people talking, you kept it interesting throughout - again, that's impressive, not to mention hard to do. I know I have problems with that. P:
Something specific: I loved Albrin's method of hiding the sphere - next to the glow-in-the-dark white sphere. That got a chuckle out of me.
But yeah, good show, Gabi. I don't think it was as dark as you made it sound, but that didn't make me enjoy it any less. Cheers!
