Second Layer of Grimworld, Tairlal Cosmos.
Tairlal Cosmos was being subjected to a large-scale attack from Griminions and members of Hollowstar.
No one from outside the Cosmos bubble could enter, and no one from within could leave. If they attempted to leave, they would face immediate death due to the presence of a Void Titan Leviathan roaming the boundaries of the cosmos.
This was the second-ever appearance of Void Titan Leviathan; its size was utterly vast. Simply a scream from it could destroy Immortal Kings into mist, and even Immortal Emperors had no chance of survival against this powerful creature.
The only restriction was that this cosmic creature, which was not a part of Grimworld, could not enter the cosmos bubbles, as they were restricted by the Grimworld Tree. It could only roam in the void outside of the bubbles.
Therefore, as this creature roamed around this specific cosmos bubble under Hollowstar's control, entry and exit were impossible.
