Okay, i know you all know about the AI terminal where they have AI seeking cyborg, etc. And i noticed that there are 4 entries, but i know of only 3 AI's in Marathon [besides Thoth]. Anyways, i noticed that the 4th description kinda matches Cortana's from Halo 3...
"SLEEPING BEAUTY. Long-deactivated
extraterrestrial personality construct in search of
gullible carbon-based cyborg (<20% machine) to
confuse, irritate and teleport randomly around an
abandoned desert planet in the core. All answered.
MRa268' (5/30). "
Notice how it says less than 20%, i just read it in the facts & puzzling things, could this be the MC? I dont know, im just rambling, please forgive me if this has been mentioned before, and sorry for the bad capitalization, its 2 am here.
