Artifact three location guide
To find the thirrd artifact, you must first find the system it is in, the artifact will not be in a listed system, but a random sector, mine happened to be in sector 1059, and I am unsure if this is for all games. Once you find the planet, you must accend the tower...Then go around the edge of the roof untill you find this door...Once you find the door, you must decend into this hole...Until you find the bottom, once you make it to the bottom, go into the lava stream and quickly pick up the artifact before you die, the lava will rise once you pick up the artifact, but it does not matter if you die at this point, after getting the artifact, turn it in.
