SWTOR - Rakghoul Epidemic Quest Line

This quest line begins just to the Northeast of Outpost Thorazan.  Just heading up to that area will start the quest.  On the map you'll see a bunch of wreckage spread in the desert.  Coming up to it you'll see Rakghouls and smoking wreckage.

Part 1:

Once you enter the area the quest chain will begin and you'll be asked to kill some Security Ensigns.  Once you attack one a group of Rakghouls will spawn around him (level appropriate) that you'll also have to deal with.  These fights aren't difficult and you'll retrieve the items you need shortly.  You should also get a few vials of blood which start a second quest chain.

After killing the Ensigns you're asked to locate security terminals.  They are small pieces of wreckage spread  through the crash train.  Generally they look like stands with keypads on them, they aren't hard to find and respawn quickly so if you get stuck just go back to the first one.

After the terminals you get to pick up two power cores.  These are larger pieces of wreckage that look like big squares attacked to cylinders.  I found one by an engine and one by the biggest piece of the ship.

After the power cores you'll get a map location to access a terminal.  When you access it an Elite will spawn that you need to kill.  He'll drop a piece of data that you can use in a nearby terminal to complete the quest and get your reward.

Part 2:

Quick travel to Outpost Largona to turn in the blood and get a short cutscene with a droid that has a hairdo like Leia.

Once you get the next part of the quest chain you'll see some markers on your map to help you locate the infected Sand People.  I chose to save them, but I assume killing them is functionally similar.  Head down into the Sand People area and you'll find some with yellow names, these are the ones to target.  You have to heal (or kill?) five of them to complete the quest.  After healing five of them you can return to the spaceport and turn in at the console marked on your map.

Part 3:

Once you enter the area you'll get another quest chain telling you to collect wrappings by killing some of the sand people.  The same yellow named ones are your targets.  Once you attack one adds will spawn (level appropriate) for you to take down.

After collecting five wrappings you're sent to investigate a downed pod, which is just a lot of running and not difficult to find, there is a marker on your map.  When you click on the pod adds will spawn around you and need to be killed.

After taking them out you have to massacre some of the infected wild life.  There should be two nearby and another a bit further along your backtrail.

Once you get three samples you'll get the next updated quest point, which is just to investigate a few murals. These are stretched hides on poles like the walls that you've seen surrounding their camps.  There are three of them stretched in a line back the way you'd come from.

After finding the third one there's more running to spawn an elite, kill him, then run to the last mural and click on it.  After all that running you're finally finished and get your reward.
