Identify series about a psychic / 'Space Wizard' who heals cultures
I read these books around 10-20 years ago via the library, but I suspect they're older than that. I don't remember enough details to google them on my own, but some key points:
* It's a series of novels where the protagonist is a psychic / space wizard who travels via ship between various worlds, and helps them correct various cultural & social issues. I think the protagonist is from a family of psychics and just decides to call himself a space wizard, but I just don't remember details clearly.
* One story that stuck in my mind has him treating a planet where a decision to require everyone to get married causes a large prevalence of individuals to develop 'megalomania' (unhappy parents -> abuse -> mental issues with insisting their nobility that has been unfairly removed from their 'rightful place'). These individuals are collected in cities controlled by a computer that came with the original colonization effort, that tries to keep these self-declared nobles taken care of. The protagonist of the series 'heals' them by taking them back to various key events in their lives and reliving them, but with the emotional impact altered -- e. 944
g. instead of being beaten for breaking a vase by an infuriated, bitter mother, they're scolded appropriately by an exasperated mother. He uses the healed individuals as a cadre to reform the planet to 'fix' the marriage requirements.
* It may be the same story, it may be a different story, but I think it included that the civil servants had a tradition similar to ancient china, where you had to 'test' into their ranks. That test was theoretically kept fair because the servants were rotated, so they couldn't favor their own children, but in practice a lot of those servants identified their predecessor's children and favored them in a wink-wink, nudge-nudge pattern that lead to them being favored anyway.
* At some point, he picks up a cat-like hitch hiker with powerful psychic abilities. In another story, this hitch hiker helps solve the issue on a planet that's torn by feuding clans by talking to the native lifeforms -- who just happen to bear a strong resemblance to the 'little folk' of Celtic myth -- to help support ending the constant feuds.
* I think there's another companion who pops up at some point, but I don't remember any details.
I'm reasonably certain the author participated in Writers of the Future at some point, because there was a WOTF story with a very similar premise when it came to curing 'incurable' mental illnesses. Unfortunately, I don't know which WOTF year it was. 1012
