Leaving that planet was extremely easy, I took everyone to my shadow, then I changed my appearance to that of a long-haired brunette woman, I stopped using the power of the Law making my wings disappear, then I walked from one city to another following the reverse flow of the Ascendants who were coming to investigate the disappearance of three level 3 Ascendants.
When I was far enough away, I simply left the planet, I never needed the Ascendant wings to fly from the beginning, I also have my Dragon wings, I used my true wings to fly away while using Spatial magic to shorten my path as well as Thunder Ki to increase my speed.
Everyone was inside Tarzor, so I was able to move away as I wanted without being noticed, if I could use my Divinity it would be an even faster trip, I needed 1 hour to reach the closest planet that was not the one occupied by Ghanor's troops.
