Okay, so lets say you are a minor deity in the D&D universe (or a Wizard, natch), and you want to contribute something to a particular society or culture. Let's say you want to contribute augmentations and improvements and things which make a society of mostly human people 'better', in the sense of the real-world Transhuman movement. What sorts of things would this creature enable?
I have a few ideas:
1.) The creature can give inherent bonuses, as per the Wish spell
2.) The creature can give useful grafts to people, as per Wish
3.) The creature can give automatic 'retraining', as per things like Psychic Reformation
4.) The creature enables immortality, via Kissed by the Ages
5.) The creature enables changing into an Elan
6.) The creature enables something along the lines of a targeted Reincarnate/Last Breath
7.) Giving access to the feats and abilities which can normally be gained via paying for them or going to obscure places
8.) Giving access to high end Permanency and the spells which can be made Permanent which can be placed on a person
And from there, I really run out of ideas. What sorts of things would such a creature whose sole purpose is changing and improving what it means to be 'human' in a population of humans do, per D&D rules? What sorts of capabilities are inherent in the system, which such a creature can potentially bestow to others? And for those options which are a bit more obscure of the ones I listed, I would love to hear some specific feedback! Any ideas? Thanks!
Edit: Do note, I only want things which can be used on currently existing people, which can improve everyone or almost everyone in a society, and not a select few. Otherwise, what's the point?
