- Portals are tears between dimensional planes.
- If the dimensional space has too many tears not only can malevolent entities come through but the tears can grow so large that they rip apart space itself.
- To stop this threat the Astral Knights must work to close portals whenever sensed and prevent space from being ripped apart into nothingness.
- Astral Challengers who travel between dimensions in an attempt to become the strongest in the universe recklessly open portals between dimensions and risk ripping space itself apart.
- Astral Challengers are also prone to attack anyone they see as strong in their attempt to become the strongest in the universe and are violent combattants.
- In an effort to close these portals, Astral Knights will be faced with combatting the threat of violent Astral Challengers.
