Mind Manipulation
The ability to influence, change, detect, or penetrate someone’s thoughts is considered mind manipulation. Among the humans and dragons of the Combined Territories, we see a number of people with these types of abilities, usuallyused for good, but always with the potential of misuse if someone were to be twisted in their thinking and lacking morals.
Grabon and Heron obviously have mind manipulation skills as they probe memories, motivations, and thoughts well beyond what someone would willingly give them access to. They do this before rendering judgment, also when someone applies to join the clan. It prevents them from making a mistake, yet the potential for misuse is huge.
Can you name other character with mind manipulation skills? As the series progresses, the number of people who have and use this skill is going to increase, but already there are a fair number of characters who influence the thoughts and feelings of others.
