When Samiel undertook the Mission assigned to him by the Hall Master himself, through Bishop Abraham Antigonus, in the end, he decided to take with himself the Ork Dharzug. As he predicted, Yvraine was not that interested in going to freeze to some godforsaken mountains when she didn't really have to and still was under the depression from our last similar trip.
Probably psychological trauma from almost freezing to death because someone forgot to cast some warming spells on herself to prevent such a situation could really run deep. At least, deeper than Samiel initially, though.
