The Little brother is a Unique investigative class that belongs to the Blue Dragon faction
Unlike the prince this character is converable. However, once the prince dies he become the new prince, and unconvertable
Night abilities
find-prince: check 2 people, will tell you if one of them is the prince
Follow prince(3 charges)- will tell you who visited the prince last night, and who was jailed by the prince
Passive: Royal blood
Passive: Become prince if the original prince is dead
What the idea:
Many games is decided if the prince died early or not, this way the games will be less random.
The cult/unseen can convert or kill the little brother before killing the prince, so it wont be like the priest meta when 2 princes were almost guranteed.
Alternative: the little brother will become the prince only if the prince died before night 4-5
Of course, you can add this class while removing 1 physician for balance issues
