Fyron

[Atrocities]

Fyron has proven himself to be a very competent modder when it comes to making quadrant mods. So this kind of thing would be right up his alley.

I guess you would have to call a mine field like this a self replicating mine field. Thus why it is still around after a millennium.

[Slick]

The "minesweeper" for these mines could use SM to convert the asteroids into a "planet" which is just another tiny, uncolonizable planet with a pic and description indicating normal asteroids.
