Celestial Garden

Originally, the Central Administration ruled most of the solar system and was led by a single hereditary emperor/empress. The last empress, as anyone can tell you, was Zephos; she is basically in a coma and kept in a hibernation state somewhere in some sort of shadowy facility (there isn’t a shortage of them, after all). After this the power formerly held by the empress was placed in a ruling council which was an advisory body when she was alive.

In fact, it vests in no such place, because in Sigeki the empress is a thousand-year immortal who manipulates you, not the other way around.

‘Zephos’ was one of the survivors of the oldKMV; like pretty much all of them on record she was somehow rendered immortal by this (though she may well have been so before, I’m not entirely sure what my 10-year-old self thought). She’s an immensely powerful air elemental, compounded by both age and job title, and her primary weapon is the original form of the Shining Laser; Michael uses a relatively accurate copy of it. Actually they share a few key points, in that they are both flying deadpan snarkers with stafflaserbeams.

…Well, technically speaking she put most of her skill points into being book-dumb and very, very lucky, so mostly she delegates the manipulation out to several contractors. Most notably Marcus Silverberg, Helena’s younger… psuedobrother with the changing name, Wizard unit number five (Helena being one, and the Psycho Prototype Primus being zero). Despite Helena being a prototype-y unit, he’s roughly equivalent to her in overall potential. Most of the reason Helena is so high above him in plotlevel is because she’s effectively a Warforged Cleric (take that).

Marcus is basically a Battle Butler. Who defends her top-secret moonbase from intruders with the help of his giant orbital dimension-warping laser. I haven’t thought of a good Bilingual Bonus Gratuitous German name for it yet, though.

I’m not entirely sure how she manages to hide her general existence that well, but… I assume a thousand-year-old superpowered human(oid) would have some tricks, and there’s also Marcus, so that can be handwaved comparatively easily.
