about that ask pertaining if time players could reset timelines, could you explain that a little more? where does it say they can do that, and why is needlekind necessary?

In order to reset the timeline you need to initiate a Scratch.  If the player’s session had already been Scratched they can’t do it again.  In order for a Scratch to be initiated someone who has Needlekind must wield the Quills of Echidna  to scratch the session’s Scratch constructed located on the time player’s planet.
