SWTOR Nar Shaddaa (Republic) Orange Mastery Datacron Location Guide

The Orange Mastery Datacron increases your aptitude in combat, allowing you to do more damage. It will grant you Mastery +3 to your permanent stats along with codex: Galactic History 34: The Discovery of Ryll. There are 5 Datacrons in total located on the planet of Nar Shaddaa.
Note: You can collect them on either Republic or Imperial Side as they count towards the same achievement.

Datacrons are collectables scattered around the galaxy in Star Wars: The Old Republic. Each Datacron contributes towards your Legacy's passive stats permanently. Furthermore, they also provide interesting Lore and Codex Entries about the Old Republic era.

Starting coordinates: -1672, 2988.

This Datacron is the same on both factions.

The Datacron is located in the incinerator room above the Prison Yard of the High Security Lockdown area. To get to High Security Lockdown take the speeder to Lower Industrial Sector and turn left (right on the map). Go through Imperial Intelligence Gadget Warehouse to the south-east corner and take the elevator to High Security Lockdown.

Turn left and go to the stacked crates at a container with a catwalk leaning on it. (directly south of the Alien Outreach Center on the map)

Follow the catwalk until you get to a circular doorway with a clickable terminal next to it.

Take this elevator to the Incinerator Room. You will be set ablaze, so you have to be quick in there. If you click the wrong button, you will die. So be sure to see the steps below before entering.

Jump down and get to the terminal in the corner and click on the line of numbers on the second row. This row has to have the code: 326:3827.
(This is an easter egg from A New Hope. This is the number sequence of Garbage Compactor 3263827 that Luke, Han and Leia almost get squished in)

Once you've clicked on the correct code, the doorway will be opened and you can enter it safely. It will take a few moments for the fire animation to disperse. You will find the Datacron on the other side of this door next to an Old Prize Machine.

This will grant you Mastery +3 to your permanent stats along with codex: Galactic History 34: The Discovery of Ryll.

This datacron holds unheard of power and knowledge collected by an ancient race. You access its power and discover writings which are clearly only one small piece of a massive galactic history:

In the years after the Great Hyperspace War, a discovery was made on the Twi'lek homeworld of Ryloth--the spice called ryll. Ryll was a component in several medicines, but was also a powerful stimulant. Sensing opportunity, Neimoidian traders quickly gained a monopoly on ryll and were keen to introduce it to other species.

One of these species was the Porporites, a peaceful people who had recently made first contact with the Republic. But in contrast to other species, ryll drove the Porporites into homicidal fury. Eventually, the entire species was composed of raging maniacs who began attacking other worlds.

Alarmed, the Republic asked the Jedi to take action against the Porporites, but the intervention was unsuccessful. The Neimoidians, fearing for their livelihoods, decided more desperate measures might be necessary and turned to Gank mercenaries for help.

Important note! You have to interact with the Old Prize Machine to be able to interact with the Yellow Matrix Shard. This will grant you a Slot Decoder you can find in your inventory. I recommend going for this Datacron right after, since it is in the same area.

Note: When you want to leave this room you can click the panel at the shield wall to the tunnel, which will lead you outside. This can also be used to enter this area for a friend.
