I use time travel sometimes when I’m running The Clay That Woke. In one game a Voice came to the Degringolade for a player minotaur and offered him something he wanted if he agreed to be sent to the future to kidnap and bring back a future enemy of it. So presumably the Voices are outside of time and know and operate throughout their whole timeline. When the minotaur met that enemy in the future it was a future version of one of the other player minotaurs, who had a name at that point, and a girlfriend who was a fierce action hero future version of a woman another player minotaur was crushing on. No paradoxes though. The player minotaur is either eventually offered that name or he isn’t. He either meets that woman and they click, or he doesn’t.
