This completely ignores the lore of legacy WOL’s and the dubious canonicity of the fact that it’s possible that all players “experienced” legacy and were sent forward by louisoux even if only legacy players “remember” it
The backstory is up to the player but haedalyn had nothing to do with it. Hell the starshower legacy players saw has nothing to do with haedalyn anyway, it’s a natural phenomenon. The only “predetermined” aspect of your player is the fact that you are a shard of azem but that’s how the aetherial sea works
