Professor Parver held the intensive course inside his lab on the hidden floor since Khan was the only student. The room's privacy gave them more freedom, allowing them to share a few drinks while going over the lesson.
Khan drank and took notes while Professor Parver explained and expanded on the many holograms coming out of the two interactive desks. The man had to take many breaks during his illness' outbursts, but the lesson flowed smoothly nonetheless. Khan could only complain about its contents.
Professor Parver's course aimed to educate on the immense field of alien environments. The subject had more branches than specialists, so the Professor had to start from its very foundation, opting for a broad and general topic that would span for many days.
