The Massiff is a hunter found on many desert planets. They are a squat animal, with a row of spines along their back, standing at roughly a meter tall.
Byager was bred in a tame condition, and is comfortable around humanoids. It depends on humanoids for survival and looks to them for support. As creature handling goes up, a member can better understand and train and control this creature, but it will always look to Grot for guidance and support. When a character is proficient (+3) at handling creatures, they can do all they need with a domesticated creature.
Byager has typical coloring and physical appearance for a Massiff.
Byager is larger than the average Massiff in terms of size and body mass. Their bulkier build can offer better power but often at the expense of the mobility and agility commonly associated with other Massiff.
Byager has grown accustomed to getting special treatment over other creatures, and likes it. They now expect to always be treated in this manner, which can make them come off as entitled and somewhat selfish.
