"I came here to this place, many millions of years ago, before mankind was even upright. As eons came and went, mankind appeared around me and found names for me. Demon... Spirit.... Tuurngait.... We existed in harmony for much time. I, lying dormant in what you refer to as "The Infected", and they benefiting from my knowledge and protection. But mankind changed and I fled. So much power in mankind, so many questions, and yet without the intelligence to answer them."
