Are you eager to complete A Shadow in the Void in Crimson Desert? This is one of the last main quests in the game, and it directly leads you to an explosive finale. That said, the clues themselves are fairly cryptic, and you might be wondering where you need to go. Our guide has all the details that you need, since we also discuss various locations in the Abyss and the series of final boss fights at the end. However, given the topic at hand, you can certainly expect major holy moly spoilers. Where to find Caliburn in Crimson Desert's A Shadow in the Void quest?The Crimson Desert A Shadow in the Void quest concerns the whereabouts of Duke Caliburn. After assaulting the fortress, Caliburn manages to escape via a portal that leads to the Abyss. The quest tooltip then changes to mention the following: "Caliburn vanished along with the Abyss gate created by Grundir. Move to the Abyss and go after Caliburn, who must be somewhere within."Your goal now is to reach the large Abyss island in the center known as Dimensional Bonds. To do this, you need to go through multiple Abyss island chains with their respective puzzles and challenges. Some branches do lead you to Dimensional Bonds, while others just have you roaming around aimlessly. There are, however, certain shortcuts that take you to that same destination as well. The Spire of Clockwork branch: The Riddle Square time trial and the Storm Veil elemental skillThis was the branch that we took during our playthrough to find Caliburn in Crimson Desert:As you can see, the main quest's objective marker is somewhere in the marshes of Demeniss. But your actual quarry is high up in the Abyss realm.We went through the Spire of Clockwork, which is further to the east. At this point of the campaign, you should already have the key that unlocks the tower.The Spire of Clockwork and the Abyss island that follows it, Riddle Square, also unlock a new elemental skill. You can learn about various tips and mechanics in our Storm Veil - Wind element guide.The next sections of our guide discuss the remaining islands that are part of this branch/chain. How to complete the Origin of ThoughtsOrigin of Thoughts is the next island right after Riddle Square:The goal is to power up the large, disc-like structure by attaching rectangular batteries into the slots. One of these batteries at the halfway point is actually hidden in a small nook below you. You can jump down and grapple it using your Axiom Force to lift it back up.Upon reaching the top of the structure, check one of the corners for a small vertical shaft. The opening has a switch that enables the controls to the discs.You then need to rotate the three layers of discs so that they're perfectly aligned.Once the discs are aligned, skydive back down and activate the mechanism in the center. How to complete the Forgotten AltarThe Crimson Desert Forgotten Altar has a rather tricky brain teaser for you. That's because there's a large fan-like device in the center that creates a deadly tornado, and you have to find a way to disable it.As you approach the area, look to your left to find branches. Burn the thorny vines to reveal a medium-sized orb.Place the orb in the empty receptacle to restore power to the facility.Ride the wind current from the fans to reach high up into the sky. Then, carefully lower yourself on the windvane in the middle of the rotating mechanism.Once you're standing on the mechanism, do your Nature's Snare ability. While Kliff is doing the motions for the Nature's Snare barrier--i.e. hold X on a keyboard or rotate the right thumbstick on a gamepad--you'll notice how the large fan's rotation is being reversed. Eventually, it will stop.Now that the tornado is gone, hop back down and approach the metal cage. Climb/hang onto the circular opening, then hold the button prompt to "Resist"--i.e. hold L2/LT on a gamepad. While the button is held down, do your Force Palm action. You should be able to activate the mechanism/plate inside the cage. How to complete Disconnected TruthThe Crimson Desert Disconnected Truth is a gargantuan island facility that has two levels. For the lower level, attach the disconnected cable to restore power to the area. This allows you to ride the lift to the upper level.Once you're at the upper level, check your surroundings. You'll see three circular power receptacles on a large generator, but only one is active. The cables from the generator also lead to various areas. Your goal now is to restore power to those areas by finding the electrified square panels.Area 1 - The electrified panel is floating in mid-air next to the giant inverted pyramid. Use the floating ledges or do a triple jump to grab it with your Axiom Force grapple.Area 2 - The electrified panel is already attached to the wall. Use your grapple to pull it out, and bring it to the upper section.Area 3 - This one already has a power receptacle that's orange by default. Bring out your lantern and follow the cables co
