I'm Zach Fair, SOLDIER 1st class. I'm dead now, but I still see the lifestream that I'm not in. What happened? Is something or someone keeping me from entering it? Give me answers!?

It has been two years that I have been stuck here alive and dead at the same time. I seem to be able to survive without the mako energy I need. What has brought me here? Why are these weird creatures here? And why haven't I seen any humans? I only made contact with these creatures and some voices, but no humans. I want to know what is going on and now!
