Please consider a small cluster of claims in the Uroborous Belt labelled DLR 1 thru 5.

I'm preparing to post another adventure called Roses In The Black, detailing the travails of the De La Rosa clan, and their factory ship, the Marie Rosa.

The Marie Rosa acts as a mothership/tender to a half-dozen Pillbugs/Prospector class, and they and their crews prospect over a fairish range- but have laid claim to five specific asteroids.

The trouble starts when someone decides to run them off their range. The heroes are called in (more or less by accident) to help defend the dignity and honor of the De La Rosa clan- and the memory of one of their own.

For those who might be interested, this is the adventure which gave birth to the mercenary Ariel corvette mentioned elsewhere in this forum. 

And just cuz I like the sound of the name, how about a "Fat Sal Mine", specializing in jewelry-quality diamonds and rubies.  The mine was originally discovered/operated/founded by the titular....um, robust....woman who was later run off her claim by an unscrupulous partner and hires the heroes to help her get back what's rightfully hers.
