There are some scientists who agree whole-heartedly with the Empire's xenophobic views of the universe. One of these is Dr. Bledsoe, an Imperial expert in the field of disease and medicine. Dr. Bledsoe has been abducted by a group of Alliance terrorists, and is being whisked away for questioning at one of the Rebel insurgence camps. Someone must rescue him before it's too late.

An Imperial colonel who is on the verge of retirement heads the rescue operations. He feels it is his duty to make sure all Imperial hostages are freed before he gives up his post. The Colonel needs a group of ragtag Imperial supporters to board the Rebel blockade runner and make sure that Dr. Bledsoe is freed before any harm befalls him. Who knows what those ruthless Rebels will do to a poor scientist who can't even defend himself properly?

Colonel Darkstone: Tatooine, Imperial Oasis (Rescue mission; -5318, 8, 2663)

Colonel Darkstone sent me out to look for Prisoner Transfer Orders.
He tells me to look in 3 areas for these orders about Dr Bledsoe's transfer.

[All these Locations can be found in your POI.]
The 3 areas he has you search are....
Wolamader Palace - Yavin IV
Corsec Base - Corellia
Droid Engineer Cave - Lok

So off I went, I hit the Woolamader Palace 1st and found nothing and then the Droid Cave and found nothing.
Then i hit the Corsec Base, and since my faction with them was +4000 it made it easy to search the area.
I did find something in a Box called a Purchase Orders and I took it back to Colonel Darkstone.

He tells me its good Info but its not what he is looking for and would take it off my hands.

Colonel Darkstone has me go back and look for more info.
So I went to the Woolamader Palace 1st and this time I found a drum that had Research Request in it.
I took it to Colonel Darkstone and he takes a look at it and said it was not the Info he wanted.
So off I go to look in the Droid Cave, the last of the 3 areas Colonel Darkstone had talked about.

I went there alone and being a Master TK/Doc I had to move slowly and not to aggro to many droids at once. I finally made it to the area that had what look like a Computer in the wall in the lower lvls of the Cave and found another Box on the floor with the Transfer Orders in it.

I took them to Colonel Darkstone and he gives me the ticket to the Corvette, and Now I have to rescure Dr. Bledsoe's

Tip:
The Boxes that hold the Orders in each area do not look like the Metal Boxes in most dungeons that we loot,
as your looking in each room look for a drum or crate that gives a search option when you click and hold down on it, once you get the item , return to Colonel Darkstone.

Not sure if the Quest will be the same for all but after talking to Colonel Darkstone I would start at the...
1.Corsec Base for the Purchases Orders
2.Woolamader Palace for the Research Request
3.Droid Cave for the Prisoner Transfer Orders

Upon using the ticket, you and your entire group (up to a maximum group size of 10 people) get transported up to the Corellian Corvette to begin your timed 60 minute mission...
