Occult specific careers for aliens and spellcasters.
I don't think all occults need a unique career option, I just can't help but notice the big potential for spellcasters and aliens in that regard.
Spellcasters could get the option for a job in the magic realm, not an active career but something more suitable for them to do than some mundane job. They could advance in ranks, becoming an apprentice all the way to becoming a circle's arch mage.
They would unlock some nice robes, wands, a cauldron and broom along the way, and some new magic interactions. It would make being a mage more engaging. Improving their spellcasting rank could be a promotion requirement through it as well, and the job only becomes available to spellcasters.
Aliens could get an earth explorer career which could be a lot of fun. It's all about learning about earth and sims. Could be great as an active career, but can work otherwise too with very interesting assignments.
Their career would unlock new alien powers, an alien rocketship with matching space suit, and some other alien stuff.
