I'd really like to get rid of LockeZ. His play style is way too unpredictable. He's always like this too. If he ran a country, he'd just kill and imprison people at random until crime stopped.
Floor was built by Gaspar after he was sent here. This game takes place before this happens. Do some research before you criticize. Thanks for your interest!
Well since there was very little information regarding the EOT before Gaspar, I had to think on my feet. In the one cutscene in CT, Gaspar is seen standing on "nothing" as he gazes into the abyss:

I simply mimicked the atmosphere and assumed there was some type of gravitational force that held everything up. This is what would contain the light portals IMP.
Please give it a try, and let me know what you think! All constructive criticism welcome. :)
