Loghrif or at least one of their shards can do time magic which sure isn't future sight, but could you imagine what crazy stuff could happen if you had a person who could manipulate time even for a short while that worked with a situation that you knew about due to future sight?

Don't forget Azem was going to go with Elidibus until they noped out and told them to look out for their falling star. Which if not future sight then it leans into the at some point down the road that we will probably never see of the WoL needing to become fully rejoined and to travel even further into the past to become Azem theory. Even though it would be cool I don't want to see it or for it to be true. I'd rather have Azem be highly quirky and have very vague future sight.
