Fragments of the Past quest is repeatable b4 you go to obi wan's trials if you only do frags part 1 and 2 then delete 3 and rinse and repeat. Well, I completed it to try to repeat Obi Wan. Obi Wan seemed no longer repeatable and I was stuck with no more repeatable quests. Until a guildie of mine said you CAN repeat Fragments 1 and 2 even AFTER you complete Obi Wan's crap.

Go to the camp where San'sii the Kursk Spawns and inside one of those little bunker lookin long houses theres "An Old Box". Inspect it and youll get the mission. You'll see a gazebo lookin palace arch where San'sii spawns. Your backpack will hum and youll get a popup. Gather the Splinters in the right corner near a pillar. Then you'll activate Fragments of the Past 2.

Now there's a treasure hunter camp near there with a dude named Xos lvl 88 silver elite Jedi wearing elder robes. Make sure you go to the back of the camp to get the humming message then kill Xos. Then go to the Tulrus Nesting Grounds inside near the back/near Sher Kar entrance if you know where that is, and kill a giant tulrus named Magma Horn.

Then go near the Old Republic Facility at the top right corner of the map and when you get there go to the right side of the facility and you'll see splinters that look like the previous ones. You should get the humming message and gather the splinters. Then go towards the Storm Lord area which is the very center right of the map and get the humming message near Phantom Bandits and kill them until you get the splinters then you get the 100k exp.
