I'm guessing you're referring to our initial attempts to colonize the upper atmosphere of Venus, using modified versions of our spiderbots to mine the surface in various ways.
In my scenario, which is fabricated as much for a graphic novel as for any other purpose, those expeditionary robotic miners, representing the apex of our high-temperature and high-pressure technology, were beset by curious equipment breakdowns and failures. Ultimately it was discovered that against all probability, an alien species was alive and surviving, with difficulty, on Earth's twin world!
In my scenario, they were the remnant of a crew of spacefarers whose ship had been damaged in transiting too close to our sun. For their purposes and their physiology, Venus was a better haven than Earth would have been.
Somehow they managed to eke out survival in the most unremittingly harsh conditions imaginable.
But their survival was a very near and difficult thing, until the bounty they discovered in our mining robots! With their native abilities and intellect, our technology designed for those conditions allowed them to leapfrog centuries of development time, and rapidly become formidable adversaries almost before we knew they even existed!
And that leads up to where you begin your militaristic adventures.
The Slaver incident was EVA using her medical nanites to basiclaly puppet master people.
The Mars Hab station was the location of this venue.
It occurs years before Bradamante is built, prior to the Hab heading to Venus colony.
