Where am I?

"By the way, what happened to the other person?" The Old Demihuman asked. 

This question gave Nial a little bit of a headache, but he chose to stay honest.

"The person is dead, I killed her," He said seemingly nonchalantly. The old demihuman raised his eyebrow while he continued to stare at Nial.

"Why did you kill her? If you were actually caught in an isolated stellar system, that would mean you were all by yourself, which is quite lonely. If you killed the other person, that is."

Nial understood the suspicion of the old demihuman but he didn't really care whether someone believed his words or not.
