Grace is an excellent choice, as is Nicole , **** for her Ether Attribute.
Entering The Hollow
When you first enter The Hollow for the Trace to the Source commission, the only direction you can go is left . Once the cutscene with Belebog Industries is completed, move left. Make sure you hit the bottom-right corner tile to unlock a hidden tile with a supply box in it.
Once you hit the brick wall , Fairy will prompt you to use the pile driver machine to break the brick wall so you can continue left. Keep moving towards the left side of the HDD until you find the magnifying glass tile.
Hitting the magifying glass tile will cause the screens in the HDD to expand upward , revealing a large square map with the boring machine and the grappling machine inside. From here, move up towards the "Sound Only" tile to begin the triangulation puzzle.
How To Solve The Triangulation Puzzle
For the triangulation puzzle , you will be given temporary control of the boring machine and the grappling machine so you can navigate them across the map towards the glowing blue goal tiles. The catch is that one machine can only handle bricks, while the other can only handle bombs .
For each machine, you can move up, down, left or right by moving your bangboo tile in those directions to push the red levers on the side of the screen .
For the boring machine, you will want to move directly upwards four times , then move right until you hit the edge of the screen . Be sure to move up towards the top corner to claim the loot box , then down and right to reach the goal tiles.
For the grappling machine, you are going to want to hit as many bomb tiles as possible to clear up the map - and because there are no repercussions. First, move directly left, then up towards the top of the map . Be sure not to hit the brick tile at the top of the screen, though!
From here, move left to claim the loot box, then down to the bomb tile to blow up the bricks in the way of the goal tiles. Move into the goal tiles to complete the triangulation puzzle and proceed with the commission.
Combat
Once the machines are in place, you will get a cutscene explaining that Grace is being attacked by Ethereals . You will need to move down and to the left to find the Ethereal tile and rescue Grace.
This combat will come in four waves - three being lesser Ethereals and the final being a larger encounter with two Elite Ethereals.

When going against the two Elite Ethereals, you will want to perform Dodges , since triggering them will prevent their powerful attacks. Since you are worrying about two targets at once, Dodges are better than Assists .
Once combat wraps up, you will see another cutscene before Grace explains that she has triangulated the location of the prototype .
Tracking Down The Prototype
With the location of the prototype revealed, a Hollow Fissure tile will appear on the HDD screen . Navigating through this Hollow Fissure will take you down a level and reveal a twisting brick-line path that leads to the prototype. First, go down and left to claim the final Hollow Observation Data, then up to heal and claim a loot box .
When you are ready to proceed, move left and up towards the prototype's tile , and be ready for the fight of your life.

Faction : Corrupted
Weaknesses : Electric, Ether

Resistances : None
The Unknown Corruption Complex is a three-stage boss fight that comes at the end of the Trace to the Source Commission. With a huge frame, powerful repeating melee attacks and area of effect damages around its body, it can prove to be a difficult fight if you are unprepared.
For the first phase of the fight, the Unknown Corruption Complex has long, obvious charge-ups for its melee attacks, and will only trigger Perfect Dodges . When you Dodge, you will want to back up since the attacks can last a while .
For the second and third phase of the fight, the Unknown Corruption Complex upgrades to ranged laser attacks and electric area of effects around its body , so back up quick and wait for the laser to turn off. Its melee attacks no longer have a charge-up and are done in three quick successions , so watch carefully to trigger a quick Perfect Dodge.
The third phase is very similar to the second phase, except combat will end once you get the Unknown Corruption Complex around half health in its third stage . You will get a cutscene with Koleda, and the commission will be completed!
