Is There a Relationship Between the Beastmasters and the Tortures?

Varian tries to strike up friendships at the bear tower and learns a little bit about their customs. He talks about how the relationship between the Beastmasters and the Tortures is actually quite similar. The specific text says they take a lioness or bear's eye in marriage and after which he shuns human women. Now that could be just celibacy. Or it could be like there's literal animal congress going on, which suggests a level of control that the bear tower guild has over their animals are really strong.
