The Last Campfire

This trophy will unlock when you've helped all the Forlorn in the Caves. There are 7 in total. Only 4 are needed to continue on with the story but all 7 are required for this trophy. For a more in depth guide on where to find them and how to complete the puzzles associated with them, please see the Forlorn/Ember Location and Puzzle Solution Guide found here: LINK. If you need just their locations without any puzzle solutions, please see below.

• Cave Forlorn #1 "Carried Away": From the Campfire, head right (past the empty mirror frame) and continue right to the next area. Follow the path up and grab the mirror stone. Bring it back to the empty mirror frame to shine a light forward. Head to the left side of the Campfire and knock down the bridge that's blocking the light ray. once on the other side, head up through the lit pathway. Hug the ledge as it curves to the left to find the Forlorn.
   
• Cave Forlorn #2 "Abundance": From Forlorn #1, head back down to the main cave area (with the Campfire) and rotate the beacon so it's hitting a mirror-like object on the far left wall. This will open up the just next to it. Climb down the rock wall and at the end of the stone path is a valve you can rotate with a lever. Rotate it so the bridge forward extends (don't turn right yet). Cross the bridge and the Forlorn will be on the other side.
   
• Cave Forlorn #3 "Turned Around": After interacting with the Builder (see Builder's Awakening), the passageway to the left of the Campfire will now be open (you need to ride your boat through it). Once on the other side, dock your boat on the far left and rip the ladder out of the wall, then move it just a bit to the left so the top has a clear path. Climb up two rock walls and go through the lit pathway. The Forlorn will be at the end of the path.
   
• Cave Forlorn #4 "A Complex Machine": Make sure you pick up the Lever that is sitting just outside of the lit pathway you went through for Forlorn #3. Make your way down the slide. Go down the wooden pathway and follow it right. Just up a small ramp is a slot in the ground. Put the Lever in this slot and pull it to the right. Go down the ladder and use the two barrels to form a path, then head left and make your way up to the central beacon. Rotate it so the light hits the beacon the right. A Serpent's Calling will unlock here. The snake will move, clearing the path to the Forlorn.
   
• Cave Forlorn #5 "Fractured Mind": From the Campfire, head right either down the stairs or down the rock wall, both work, and head right some more, then up a rock wall. Go through the lit pathway. The Forlorn is at the very end of the path, just past a skeleton.
   
• Cave Forlorn #6 "Into the Dark": When you did the sequence with the Builder Robot, you should've picked up a Spindle Arm. You'll need that next. From the Campfire, head down (either the stairs or the rock wall) and cross over the metal bridge. There will be a valve without any handles. Interact with it to place the Spindle Arm on it. Rotate the valve to split the bridge. Follow the wooden path back to your boat (push the two barrels - one into the water and one to complete the path). Get in the boat and make your way all the way right, past the bridge you just opened up. Dock your boat on the far right ladder. Move the Cylinder out of your way and head to the next area on the right. Go up the stairs and pick up the Golden Statue. Place it on the square platform just to the right of the Beacon. Climb down the rock wall and get inside the large wooden wheel. Run inside it until the platform the Golden Statue is on lowers down and the platform that was once on the right is now on the left. Move the Golden Statue from the back platform to the front. Get back in the wheel and move the platforms to their original positions. Climb up the rock wall and go all the way right, then down another rock wall. Pick up the Golden Statue and place it in the hole in the wall. Climb back up the rock wall and now the path to the Forlorn is open.
   
• Cave Forlorn #7 "A Brief Journey": In the same area as Forlorn #6 is a beacon you need to light (the mirror is right of the Beacon and the frame is goes in is up the stairs). When the beacon is lit, turn it left so the light is going through a hole in the wall on the left. Head back to the area on the left. Climb up the first chain and rotate the Beacon so it's hitting the stationary Beacon in the back. Climb back down the chain and then up the rock wall to the left. Rotate the Beacon up top so it's hitting the stationary Beacon on the left. The snake will move out of the way, clearing the path to the Forlorn. Get in your boat and dock at the far left pier to reach it.
