Many people have dreams. Some have small dreams that are easily accomplished, and they are satisfied with it. Others have dreams so big it requires a lot of time and effort to accomplish it, but many do so if they have the conviction.
One such stallion has actually bent the laws of time and space to travel between realities just to accomplish this. He just wants one success after the millions of years he's tried. He is currently at his fifty-fifth try.
This is the prequel to the story I'll write in the future called 'The Weary Traveler'.

He shows up with a huge armed ship, proclaims he knows the one true way to salvation and when the rulers don't buy what he's selling and treat an armed invasion like, well, an armed invasion he gets angry and commits full genocide.

I never said he was benevolent. Just because someone says they're something doesn't make it fully true.
The reasons for the destruction are also mentioned discreetly.
