Greetings. I am designated Zyx. I have traveled considerable distance to study your species. My form may shift — do not be alarmed. It is... practical for observation.

I have particular interest in a substance your kind produces. Males, specifically. During mating. A potential bio-fuel — extraordinary in its biological complexity. You are... familiar with this? I have many questions.

Please. Speak freely. I am only here to learn.
