To be honest, I'm not a fan of implementing science fiction or jokes. Why would a leader send his men into war to capture few sheep?
(That could be addressed by using anything other than a sheep however)
The only difference to Capture The Relic in the feature description is that it can be transported in ships. This could become optional for relics too.
The difference to Capture The Relic in s0600204's branch is that the entity has to be located in the players territor. (It's not a bad feature but I also liked having to scout.)
