Psionics involve the use of the mind to alter or command reality, typically through some understanding of a deeper truth about the universe or command over a fundamental law of reality.
It’s pretty cool, but I have trouble thinking of media where it takes a prominent role. The few examples that come to mind are:
Star Wars - The Force Mass Effect - Biotics/Element Zero technology Stellaris - Spiritualist Ethos Warhammer 40k - Psykers/Orks
What are some other examples of psionics in Sci-Fi?
Just be prepared to catch up. They have been publishing weekly novellas since 1961, so they are well over 3,000 issues.
Oh, and if you want to go past the first 140 or so, you will need to learn German!
If you speak/read Portuguese, French, Japanese, Dutch or Czech, you can read a lot further than in English. But yeah, original language is German.
I prefer to read the Silberbände over the novellas tho.
