Feel free to walk around and explore the mothership, and talk the various companions. Once ready proceed to the open door a the top of the map.
Once there you will be auto prompted with some general instructions.

Now on the lower level of the mothership you can choose to go train in the combat simulator on the left side of the map, talk to more NPCs, Save (purple crystal across from elevator) or go directly to Mother (right side of map) to advance.

If doing combat, you will be prompted with a brief tutorial if you so choose. Please follow this tutorial if you are unsure how to fight.

When speaking to Mother for the first time, she'll give you a mission log, which you can reference in Key Items if you forget what you were doing.

Talk to Mother again for more backstory, or go to the "Are we ready to land?" prompt to move onto the next area.

After the cutscene you will find yourself stepping onto the Earth-like planet of Locus. Proceed toward the right of the map.

It is here the Orphans will encounter a hostile alien race. Interact with the two to proceed.

After finishing the fight go to the next map. Explore and work your way through the forest toward the right. The most immediate path through is through the gap in the trees at the top of the map. However in the bottom left corner, and in the top right corner of the map there are items that can be found on dead bodies. As well as a item in a log near the body on the top right.

On the bottom right side of the map you will meet the first of the alien race that is not hostile. Speak with them to proceed.

Interact with the small bushes on the right side to go through to the next area.

4. Trill Outskirts
