[Wormhole generator (Chroniclers)]
[Technology level: 0]
[Introduction: This is a path that has never been imagined. We have never thought that we could solve the huge energy required to create wormholes in this way. This is enough to be called a major technological innovation. With this wormhole generator, we can create a wormhole channel in any observable galaxy within a certain range to achieve superluminal travel similar to a simple stargate.]
