Both
The Strange and
Numenera rely on the Cypher System, and that means that a lot of the stuff made for one game works perfectly in the other. (For instance, here's how Numenera character foci might be sorted to work under the various laws of The Strange):
Although the games are different, their core mechanics are the same. Both rate tasks and difficulties from 1 to 10, and both have characters who use Effort, skills, and assets to reduce that difficulty, and both rely on the roll a d20 to see if those tasks come off successfully. The characters in each are described by a single sentence: I’m a blank blank who blanks (I’m a Mad paradox who Separates Mind from Body). Even many elements of the games are similar in a general sense. So although the types, creatures, cyphers, and most of the descriptors and foci are different from game to game, the form in which they are presented, and the way they fit into the game as a whole, is the same.
Which is a long way of saying you can use most of the descriptors and foci presented in Numenera Character Options in your game of The Strange. In many cases, only a few easily-made tweaks is enough to offer your players a particular focus or descriptor when they translate to a new recursion, and in some cases, even while they remain on Earth.
