Ravian

The Ravian are a race found in Weird Worlds: Return to Infinite Space. Like the Kawangi, they only appear in a special quest. These aliens are insects that feed on planets like locusts. This race is always hostile and aims to destroy your home planet, logically befriending them is impossible. Unlike the Kawangi they are only triggered by visiting a random planet.

Event:
The Ravian are triggered when you visit a planet and see the following message

For a period of time nothing will happen. Then you will get another message.

The bugs will begin a route starting off screen and ending at your home planet. You must destroy all enemies to survive. Once the Ravian reach hope you lose the game.

The Ravian flotillas are weak individually but are usually found in swarms, making them hard to deal with.
