either its just a scienery or SE is pulling what they did in 1.0.
in 1.0, the Dalamud moon started as just a Bright red dot in the sky, but gradually increased in size every patch ( it wasnt obvious by the way, i just always thought it was a NORTH star ). every patch they added hidden contents ( that was not even announced directly in the patch notes ). other hidden contents was also incorporated with PR players ( GMs status ) appearing in game to interact with players pretending to be news writers, players was actually able to interact with them and one or more lucky winner will get mentioned when they make a post in the lodestone.
it was a nice aspect to the game that was not announced and it felt great to partake when you discover it. it wasnt game changing if you don't partake, you just miss out on story/lore
i do hope they do it again.
