These demons are very special as they come from high up positions and have authority since they are close to lord Hades. They see to it that those in the underworld within his realm are put where they need to be and some even guide astral travelers to this great god playing a role as his devout servants, commanders and gate keepers. Their appearance ranges from half animalistic to humanoid demons that are attractive but can be frightening if you are not used to this type of look. They are almost all serious with a extreme sense of duty to their god and when having a human companion it will be the same for you as well. Know that these entities are to be respected and not ordered around but rather asked. They do not take kindly to mistreatment. They can be very dark to black arts so this is something that you may want to specify with preference. Their abilities will be hunting down entities who mean to harm you and humans who seek to cause you issues in the future. Sometimes it is part of our path to go through certain things though unpleasant becuase of experience but if it is not necessary then the demons will try to make that event avoided.
