Re: WWYCD: "I, For One, Welcome Our New Insect Overlords"
*flexs knuckles* combining his knowhow of magic, his experience as a planewalker, and what he's picked up about human technology since being stuck on Earth, and what he can gather about the Mantii tech -
( are they Thri-Kreen, btw? Vitus got on quite well with Thri-Kreen )
Negotiate a crash technology mash-up.
Build and boost to orbit a thousand or more giant transparent super-rubber balloons, inflate, and line the insides with a transparent gel as growth media and puncture-sealant.
Seed with fast-growing feed-crops.
Use magic, genetic engineering, or whatever to recreate a species that up to now Vitus had never ever wanted to encounter again.
Giant Space Hampsters.
Turn them loose inside the bubbles, and harvest as required.
With the Mantii ships bringing in raw materials from the Asteroid and Kuiper Belts, and the birthrate of hampsters, within a decade there'll be a ring of kilometre-wide hampster-stuffed bubbles around the Sun, and the Mantii will never be short of food again.
As far as letting them govern Earth, why not? It's no fur off Vitus's nose.
