Player Classes are something Players choose to be after choosing Gender, Species and Homeworld(Up to GM on all of them)
Ofcourse, if the GM allows, here are some Special Player Classes(Limited by GM's discretion) (Link will be available asap)
IF you are a Xeno, some of the alien races may have special classes, those can be found: here Others not sharing your species cannot start as one of these classes, you must either go before your species council, or, if the class does not require approval, must be willing to take someone under your wing to train.
Below are what game each class is from(some are pulled from WFRP, some are custom made)
