"Eden Prime is a clear example that your people can not only make thriving colonies, but defend them equally. But how safe is it really?"

— Nihlus Kryik on Eden Prime.

Eden Prime (known as Olos Trak to the protheans) is the second planet of the Utopia system in the Exodus Cluster. After the discovery of the Mars Archives in 2148 CE, the Phase One Colonization Initiative was put into action, and the newly formed ExoGeni Corp sent expeditions to Alpha Centauri, Elysium, Terra Nova and Eden Prime. The second extrasolar human colony, Eden Prime flourished and continued to do so before 2180 CE, where it became one of the most popular tourist hotspots in the entire Alliance, often compared to Hawaii on Earth. After the geth attack however, its population decreased when fears of further attacks began to eat away at Eden Prime's tourism industry; the beginning of Collector abductions a year later only heightened this fear.
