Ilum Datacron Locations
There are 5 Datacrons on Ilum. All of them are located in the Eastern Ice Shelf. Special thanks to Beefcake on Darth Malak beta server for helping me locate and confirm these.
Datacron 1 - Republic and Empire
(Red Matrix Shard)
This Datacron is located on top of the Republic base in the Eastern Ice Shelf. It is inside one of the huts that are on the roof. You can actually get this one very easily. Go to around 377, 635 at the west entrance to the Republic base. As you are facing the Republic base above it, you will see what the huts. You will slo see waht looks like two chimneys billowing smoke. The hut with the Datacron inside is sitting next to the chimney on the left. To get to it, go up the snow on the right side of the entrance to the Republic base. Be careful of the level 50 elite guard that patrols around the area.
Corrdinates: 543, 543
Datacron 2 - Republic and Empire
This Datacron is located in the extreme southeast corner of the Eastern Ice Shelf. You have to run through a snow storm, and the exhaustion zone to reach it. Nothing to be concerned with here really. Republic players, this is located behind a heroic area so be careful getting back there. The heroic area is friendly to Imperial players.
Coordinates: 924, 1076
Datacron 3 - Republic and Empire
This Datacron is located in the center of the map inside a canyon. Its really easy to get. Go to 266, -124. The area is guarded by Republic troops on one side, and Imperial troops on the other. So both side can get to the spot easily. At that location just go down the ice blocks into the canyon. You can also use elevators at the location. Once you are in the bottom of the canyon, just ride over to teh right side, and collect the Datacron.
Coordinates: 103, -78
Datacron 4 - Republic and Empire
(Yellow Matrix Shard)
This Datacron is located inside a small building just outside of the Imperial Base. It has a few Imperial guards near it, but should be no problem for Republic players to get to.
Coordinates: 311, -380
Datacron 5 - Republic and Empire
This Datacron is located in the far northeast of the Eastern Ice Shelf. It is on the back side of a heoic area. The heroic area is hostile to Imperials, and friendly to Republic players. The start point for this Datacron is at 963, -1065. At that location you can go down an ice ramp into the large ice chasm. Once you are on the bottom, go all the way to the other end of the chasm. There you will see a cave on the right side. The cave entrance is at 309, -1351. Iside the cave go straight to the back from the entrance. The Datacron is hidden in a nook behind a large green crystal.
