Earlier before the pantheon got inside the hotel Loki had gotten to the entrance. They quickly realised that the entire building was trapped under a shroud of non-existence.
Powerful enough to keep space within the hotel locked from the outside world.
Breaking down the entrance wasn't an option. Neither was any spatial transportation.
And that left getting the task or getting in to the only Pantheon member capable of bypassing even spatial obstructions.
When the others arrived Kali was able to use her dominion over time to send a projection into the building's past. Before the Void Entity locked it off from the outside world.
That way she was able to pull in the others and herself through this opening point in the past before proceeding to take them back to the present.
Loki was still puzzled about how exactly it worked.
But at least now they had the Void Entity in sight.
