The_Scoutman i think rodak is the last big slate of investment. based on the information about "gathering philon" variable don't think we can have any sort of investment here. and the renthnorian wilds don't strike me as a big investments place.
yes "Ghenalese Finery" seem at scam, at the moment, but i want more time to evaluating the investments as whole for make a feedback for SL.
the succubi are fluff at the moment, i'm not sure will not change in the end. [they come from renthnorian wilds]. for the skullpounder i advise against skipping him. he was create by the anak, and if you don't discover the fact xestris will never tell you of it, so the information can be relevant in the future. {and at the moment i see fuzkao totaly skippable in any context}
