Hallway of Choices (Realm 1)

Hallway of Choices (HoC) is located in Realm 1 near the Intermediate Towers Sign, head near the sign and approach the rocks behind it, it is very hard to see but, at the dirt spot, you will see a slightly dark part of the wall, if you enter, you will enter a colorful room along with HoC.

It is pretty hidden in the Difficulty chart, but yet easy to find, go behind the chart and you'll find its place in the Difficulty Chart.

You can also fly by it in the Copter, but it has some barriers to keep you from cheating.

HoC's Difficulty is combined with Easy, Moderate, Hard, and Harder, as the portal shows.

SPOILER UPCOMING.

At the end, you obtain a badge, and...

a pIzZa.
