Kailen made a tear in space and left the moon immediately.
He did not take any spaceship from the Skull Chamber of Commerce after killing Dreadmaw. Those ships were definitely tagged by the Skull Chamber of Commerce. Using them would reveal his movements and actions to the Skull Chamber of Commerce.
Also, he didn't know what kind of grudges people had with the Skull Chamber of Commerce. Travelling through the starry sea in their spaceship was literally inviting the enemies of the Skull Chamber of Commerce to target him.
The remaining journey to the Imperial Sector of the Empire was smooth. Kailen was extremely careful. He sent his shadow hounds and other shadow creatures to scout several distances ahead of himself in order to avoid obvious danger signs during his travels.
Kailen currently stood at the outer perimeter of the Empire's Imperial Sector. It was a whole galaxy.
