User blog comment:Agentsmit58/Shepard's story has truly ended and wont have DLC to continue the story!!!/@comment-5124423-20120530184218/@comment-5124423-20120601115125

@Traditionalfire I mentioned the Protheans because the series is about them:

In ME1, you have the Mass Relays, the Citadel which were thought to be made by the Protheans. There is also Eden Prime, the Beacons, Feros, the Thorian and the Cipher, Ilos.

In ME2, we fight the Collectors and discover that they are mutated Protheans.

In ME3, we have the ruins on Mars, the Crucible, Javik and Eden Prime again (if you get the DLC), Thessia, the Prothean VI.

You continue the war the Protheans lost.
