Even with how vast Euri's world was, Arad had almost swallowed it whole by this time. He only had the main planet left and the dead sun.
As he wanted to leave Euri and his planet last, he headed past them and reached the center of the solar system, where the sun should've been, and he found it.
A while dot of smoldering iron, radiating with pale light as it still retained much of the sun's heat. This was the corpse of a sun, what would be left after the great titan devoured all its power and slowly faded away.
The sphere of iron was so massive and vast that Arad felt small flying around it. It even dwarfed the Mortal World and emanated a harrowing gravity that it almost ripped Arad in half and crushed him on its surface.
Arad still managed to fly, but just barely. Not because his wings were powerful, but only because he could use his own gravity magic to resist. If not for that, he would've been long dead.
