Helpful Astro.

The bot was silver. It looked vaguely humanoid with two arms. But its torso ended in a round ball that it used to move itself around. Its face was a digital screen that displayed emojis for facial expressions. To complete the ensemble, its voice came out of a speaker by its throat. 

It said, "Honored guest, I am Astro 143. You can call me Astro. What can I do for you today?"

Wrath was examining the bot all over with interest while he communicated with it.

He asked, "What do you have?"

The bot offered him a tablet as it said, "We have a wide range of products that might interest you. Take a look at this to see if any of them catch your fancy."

He took the tablet and went through the catalog of slaves they had. They had human and non-human slaves, which interested him immediately. He decided to see what kind of races they would have on offer.
