Farcosia ingredient Boraxis: what is it?

By W00KY, in Dark Heresy Gamemasters

Hi there,

I bought my copy of "Purge the Unclean" two days ago and recently read the description of the drug Farcosia and one of the ingredients is Boraxis from the deathworld Dusk. Since one of my players (a mindwiped techpriest) is from that world (or at least his first memories are from a hospitalum of a Magos Biologos living there) I intend to create a follow up adventure for "Rejoice for you are True" where they investigate how that stuff got off of Dusk.

However there is no description of what exactly Boraxis is, except that it is a "biotoxin". My intention is to create some creature that it could be from as well as an organisation (either a cult or some smugglers) that hunts these creatures and exports them (dead or alive). But the specifics elude me, escpecially since Dusk is closer to the warp then most worlds so the atmosphere, enemies and dangers should reflect that special flavour.

So, anybody have some material about Dusk or at least some ideas? Just something to get my imagination running as I am currently drawing blanks.

Some more background information :

The PC's will land in the local AdMech fortress dedicated to monitoring Dusk as well as studying the effects of long time exposure to the warp on the biosphere of Dusk with the ultimate aim to find the reason for Dusks strange phenomenas.

Boraxis could be the 40K equivalent of the chemical Borax . Perhaps it's rare in Callixis, but abundant on Dusk. The natives have no idea they are washing their clothes in a the building blocks of a black market narcotic.

It's a compound derived from the spittle of a Duskan Mud Leech - it can be used as a preservative (hence the Borax reference).

...Or whatever you make up. gui%C3%B1o.gif
