Onyxx was definitely against her sneaking into towns by herself in this time period, especially at night. Either he would mug somebody, or he would waltz into town in all his "mountain man" glory, but the thought of some drunk, grungy outlaw getting her was...less than pleasant. For a moment his eyes grew dark, and then it passed. "We'll mug somebody." He really didn't have any real problem with it. He didn't plan on injuring the guy they would mug, more than absolutely necessary for the removal of clothes anyway.
And then he got a brilliant idea. His eyes lit up, and he held one large finger up in the air in triumph. "EARTH SPIRIT!" He looked down at her, eyes bright. "We'll tell them I'm an earth spirit and that it'll be bad juju if they lay a finger on me!" And then if they do try to attack me anyway, I can't be blamed for hospitalizing them, he didn't add.
