[Welcome to the Tower of Destiny!]
In contrast to what many believed, this place is not only reserved for the [Golden Star Academy Entrance Exam], it's an actual area that would appear later in Universal Descent.
It was in fact, one of the three [Universal Towers].
[Tower of Destiny - Impossible Difficulty - Rank 8 Area]
Many people backed away as they saw the difficulty warning, but they didn't have to: after all, as in the name, it is a tower, meaning that there are upper and lower levels.
The ranking it was given was based on the highest level available, meaning the one you needed to complete to conquer the tower.
Of course, it was the same for the two other towers, though this one was the easiest among the three, as it only went up to level 1000.
They were allowed access specifically for this event only, which meant that no one would usually be able to return as they crushed the tokens.
No one except for Alex, duh.
Ding!
