The planet was accidentally discovered in 2071. Actually one could colonize the planet, but because of low amounts of minerals and ores the planet didn't get the Prime status.
In 2076 a small group of researchers spotted a giant anomaly - called Anomaly Grinberg - which turned out as some kind of portal to a unknown place. The anomaly was named after the leader of the group which discovered it. Researcheres tried to locate the exit but after a terrible failure in 2077 the project around the anomaly stopped and the area around the anomaly become a exclusion zone.
