Didn't you know? All the skeletons are female - the result of excessive dieting^^

It is easy to tell the gender of a skeleton with a high degree of certainty. There are several indicators. In an RPG the easiest way would be to look at the angle formed by the pubic bone in the front. 90 degrees or less would usually be a male.

The top one is Female. The one below is male.

The question is not, Can they reason? nor, Can they talk? but, Can they suffer?
