Kollin, the third planet in the system, is home to the Nanairo Planetary Patrol (NPP). Here you will find several places that will help you on your journey to defeat the Krawl. Once you arrive, there are at least three places you will not want to miss. The first is the recovery item shop to the west. From your landing point, head to the left until you hit the edge, then walk around and talk to the man inside the green ship. He will have several items you can buy (note that you will only be able to buy a few items the first time you visit). Stock up now using the cash you've probably been dying to spend.
The second and less notable shop is to the south. From your ship, walk to the entrance to the headquarters, then head south until you hit the end, then head left and down a couple more sets of stairs. Head right and talk to the man standing inside the large orange ship. He will have a set of mining tools to help you with future mining expeditions.
If this is your second time on Kollin, you will have to go to headquarters and save Commander Grant. Go to the large building in the middle of the area you land on, and head in. Go to the commanders office like you did the first time you came for equipment (note: you will be fighting a leader Krawl at the end, so try not to get hurt in the battles inside the building. Actually, you might as well run from all of the battles unless you're REALLY desperate for experience.) Once you arrive, Rallen will run over to Commander Grant, who is about to be attacked by an enormous Krawl. Rallen comments on its size, then runs to fight it.
