So it looks like Astellia Online and Astellia Royal have shuttered early, as spotted by Connor over at MMO Fallout. The two MMOs were slated to sunset on October 29th, but it seems the switch got flipped early, as both games are unreachable now.
Yesterday it was announced that the buy-to-play version of Astellia was being shut down on October 29th, less than two years since it first launched here in the West. Now, a day later, it's been made known that the free-to-play variant, Astellia Royal, will be following suit, shutting down this October as well.
