Artemis. Operation Stargate, #6

On every planet there are some species of animals that are becoming extinct for many different reasons. One of the biggest reasons is the destruction of their habitat and from overhunting. To save these animals it was decided to create a Sanctuary reserved only for animals. There would be no colonists and no hunting. They called the planet Artemis. The humans were chosen to be the custodians of Artemis.
The Guild of Game Wardens was created and they set up Observation Post all over Artemis, not only to watch over the animals but also to prevent illegal hunting. Everything was going well for decades until the day it was suspected that a star-gate existed on Artemis. That was the day when the peace and tranquility of an animal paradise came under threat of coming to an end.
