Some classes, such as Druids or Rangers, may be able to avail themselves to animal companions.
An animal companion may fall under the influence of a powerful domain lord. A character's companion doesn't forget its friendship, however, and will not attack the character even if a darklord directly commands them to do so. Animal companions in these situations often flee to resolve their conflicting loyalties.
These animals often shadow their masters from a distance, fearfully spying on them. If the animal companion leaves the darklord's domain, its behavior returns to normal.
Animal companions are not Dread Companions.
