As a quest lover, I can say this is one of the most horrible quest in game.
For this quest you need to bring back the specific items to the npc (questgiver in front of a tent).
To start this quest talk with the npc. He will ask for an item. See message in yellow in your general chat log. This can be alliance badges, medical supplies, bag of runes, bag of components (this is the big bag with the name bag of materials), medicin bottles, and other types of supplies. This quest is timed with only 6 seconds per item, and you need in total 5 items in a row correct. (Sometimes you can get more items together so order does matter). When you click the item, run directly back to the npc and he will shout for a new item (new yellow text in chat log). If you are too late a red text will appear on your screen and you will have to start over with getting new items (it's not needed to repick the quest).
Tip: Only pick items inside the tent (they are all in there). Outside will take too long. For this quest you need a bit of luck (it took me 3 hours divided over 2 days). Check where the items are before you start so you can memorise where to run to. It is managable without a speed potion.
