Ah, you mean moon vanguard instead of the pilot class. Well, all the other base pilot classes have been picked, with even a moon vanguard inside a full mecha, and that's a pretty awesome backstory, so go ahead!
As lv12 gestalt characters we're probably at least somewhat significant figures in whatever area we usually hang around (for reference, Oslecamo's SRW NPC stats put a pair of protagonists at lv7 and their commander at lv10.)
Don't take those as hard guidelines. I intended to make NPCs of all levels between 1-20, however time is limited and stuff.
Plus I had planned to make higher-level versions of those same protagonists.
Kyosuke eventually upgrades to the Alteisen Riese, Sanger gets the Grungust MK III. I have rough plans for an Einst base pilot class (more of a mecha-scale monster actually, but can be combined with already existing mecha), that Excellen would multiclass into for her higher level version. Then there's also planned the Machine Cell pilot prestige class and a bunch of other stuff I never could find the time to do so. But now that I sparked some interest for all this stuff, I may finally get the motivation to crank them up.
Anyway, at 12th level you definetely rank among the top elite/veteran pilots. As far as you know, only some other people out there could take you one on one, and then only a few of those would actually have a clear advantage against you. Alas, it's a big universe out there, who knows what may be lurking in the stars...
