Woops I totally forgot to actually write down the Quesh stuff I brainstormed over the weekend XD It's nowhere near as good as the Xiis brainfart but maybe it's got some things that'd be of use so here goes *cracks knuckles*

again there's not an awful lot on Quesh lore-wise, and its been forever since I played the Quesh storyline in SWTOR so I don't really remember any of it xD

-So the toxic atmosphere is apparently important to makng (adrenal) stims so perhaps Lon and his followers make use of this in an attempt to somehow make themselves more powerful than the Qyaari (kind of like the [url=http://starwars.wikia.com/wiki/Power_Guard_Enhancement_System]power guard project[/url] from the Consular storyline of SWTOR? I know they'd have Force abilities etc but what if they were trying to develop cybernetics or something that used (adrenal) stims to heighten their Force presences even further in an attempt to be [i]more[/i] powerful?)
-If we go down this route there are supposedly abandoned Imperial research facilities there which they could make use of for that purpose
-The toxic atmosphere could also be a kind of deterrant so alternatively they could simply use Quesh as a base of their operations because it'd be harder for people to drop in on them unexpected? (kinda like Zinuthra's mountain ranges)

OR 

-along the same vein and still looking at stims, what if Lon and his followers managed to set themselves up on Quesh with the goal of trying to monopolise the (adrenal) stim market in their favour, so they control all the production and exports of stims and thus attempting to win favour/more backing from powerful people and turn them to their side against the Qyaari/Alliance so they could depose them and set up their "Force user government"? 

Thoughts/Additions/Subtractions? XD
