 Arc 2 starts in Celestia, we learn a brand new form of magic, Astral Magic. We are tasked to restore the Grand Astralab which will open the trail of spheres. To fix the Astralab you need 3 Astral Relics, Sun, Star and Moon. The Star of Celestia is located in the Stellarium, however we must rebuild the Teleporter. The pieces are spread out in the Survey Camp and the Grotto. The Moon of Celestia is in the Lunarium. To get there we have to rebuild the Teleporter, it is stuck in Storm Riven. Once we collect all the Teleporter pieces we find one is broken. The Archivist teaches us how to fix it and we open the Teleporter to the Lunarium. The Sun of Celestia is in the Stellarium, the Teleporter is broken and we need to find the pieces. We get the first pieces from the Science Center, but the last are in the Crestation Empire. Here we find the final Teleporter piece and retrieve the Sun of Celestia and open the trail of spheres. Inside there are 3 levels, we get to the top and come face to face with Morgenth. She explains Celestians denied her access to Astral Magic. She concludes by stating a prophecy. The Mirror will break, the Horn will call, from the shadows I strike and the skies will fall.
