I've got character generation notes for the Chamax "aliens", if you wanted to play one (or generate some NPCs for an interesting encounter). Just to clarify, this is for the intelligent "aliens" originating from Chamax, not the bugs to which we usually refer.

These aliens are maybe up to twice the size of humans, but are horizontally aligned rather than vertically. As simple laborers, they tend to be good at excavation-related tasks. They tend to excel as low- and moderate-tech mercenaries.
Career process begins at age 10.
Aging rolls occur every 20 years; a failed aging roll results in death rather than characteristic reduction. If a character survives the roll, its caste increases by 1.
