After killing the Titan, Khal was teleported onto the planet that was at the other end of the Celestial Pillar. However, the sight he was welcomed with once he got to see the scenery on the planet was far from what he imagined to see.
Although Khal didn't explore his planet as almost 90% of the cultivators that succeeded in reaching the Fifth Realm, he had a rough guess of what resided on it and what he could find if he wished to. Though, the Titan's planet was nothing compared to his.
Khal's planet was a planet filled with oceans, forests, and vast grass fields with a few cave entrances here and there. On the other hand, the Titan's planet was nothing but floating islands all around the place, each connected with wooden bridges with one another while the boiling planet core was visible to the naked eye if one decided to look down at the edge!
