You're a genetic dwarf. Abnormally small for your species. You are approximately 60% of the height for your species and are either "cute" or "repugnant" to others of your species, and maybe others. Your move is -1 from the species base move and jumping distance is based on only half the jumping skill. Note that a dwarf Wookiee would only be slightly shorter than a normal human and a dwarf Ewok would be smaller than many dogs.
