If you want to order a squad of these you can give them a call or purchase them directly from the website. Details here.
If these figures are a complete mystery to you then you might want to look here, here, here and here.
Here's what the Foundry website has to say about these figures:
We believe that these newly discovered items are the almost
mystically rare deathcasts of the elite
EMPIRICAL ABSOLUTION and LIQUIDATION
SQUAD. We estimate their value as somewhere in the region of an ENTIRE GALACTIC
EMPIRE, probably with a couple of lost mythical lands thrown in.
The Empirical Abs etc. demanded absolute and immediate
unthinking obedience to the Empiricator [BLESS HIS NAME!] and not only from the
inhabitants of Known Space, but also from the entire population of the
Multiverse.
Indeed: after a boozy afternoon of high stake rune casting
and seven episodes of the most sacred tapes of STARTREK, the EALS (as they
liked to be known) took to speculating as to what their ultimate rewards would
be for their lifetimes of ceaseless holy work:
At this point the Empiricator [BLESS HIS NAME!] got a whiff
of what was going on. He sighed heavily, made a few passes in the air, clicked
his heels together twice, shouted SHAZAM! And he had obliterated the foolish
boozy EALS. All that was found was a neat pile of bleached skulls. Each bore
the word HUBRIS and each had a tiny lead ceremonial Manikin perched there on
its dome.
