Part 1

In Part 1 of our Dimhaven: The Lost Source walkthrough, Emily arrives on the mysterious island of Dimhaven and begins exploring the deserted arrival area. After solving a malfunctioning visa checkpoint by rewiring its answer buttons, she gains access to the island and starts uncovering clues about its strange history.

Along the way, she collects the Photo Challenge Pamphlet, completes several photography objectives, retrieves useful items and money, unlocks the abandoned Visa Office, discovers notes and lore about the island, and obtains the key to Bay Tower.

The chapter ends with Emily restoring some power to the area and using the newly found key to enter Bay Tower, setting up the next stage of her investigation.

In Part 2 of our Dimhaven: The Lost Source walkthrough, Emily explores Bay Tower, collecting important items such as the Medical Access Card and a rubber tube while piecing together clues from a map puzzle.

After siphoning fuel from an abandoned boat, she powers up the island’s generator, restores electricity to key areas, and lowers a ladder leading to a bird’s nest where she finds a missing lever. This allows her to activate the payphone and receive a mysterious call.

Emily then unlocks the Ambassadorial Lavatory, spends her collected Forints on snacks to lure away the bird that stole her passport, and completes several photo challenges around the landing bay.

The chapter concludes with her reclaiming her passport, reaching the final visa checkpoint, and obtaining a clean sponge needed for future puzzles.

In Part 3 of our Dimhaven: The Lost Source walkthrough, Emily finally gains access to the island by completing the visa application process.

After earning the “Squeaky Clean” achievement by cleaning her camera lens, she solves the filing cabinet puzzle using city name codes to retrieve a typewriter ribbon and visa documents. By comparing visa records with a sample ticket, Emily deciphers the perforated code on her own visa ticket, creates a valid visa using the blue typewriter, and successfully passes the final immigration checkpoint.

With her paperwork complete, she leaves the arrival area behind and begins her journey along the Hiking Trail to Kishvar.

In Part 4 of Dimhaven: The Lost Source, Emily follows the hiking trail to Kishvar, where she meets Old Lars and agrees to repair the hotel’s electrical system. After exploring the cable car station, she solves a series of environmental puzzles by repositioning makeshift bridges, restoring a control valve, and deciphering the Vosh lock code to enter the workshop.

There she collects key converter components, a portable music player, and clues needed to restore power to the elevator and main gate.

With the electrical systems back online, Emily retrieves the Engineer’s Key, unlocks the cable car controls, rides the elevator to the upper level, and discovers a strange key that opens the way to the next area of her investigation.

In Part 5 of Dimhaven: The Lost Source, Emily ventures beyond the cable car station, speaks with a mysterious man in a white suit, and gathers the remaining power components needed to restore the area’s machinery. After configuring the distribution panels, she unlocks the workshop cabinet to obtain the missing hotel fuses and station wrenches, repairs Old Lars’ fuse box, and is rewarded with the key to his tandem bicycle. Using the bike chain to reactivate the water wheel and reconnect the station’s power network, Emily finally brings the cable car system back online. With everything operational, she boards the cable car and leaves Kishvar behind, continuing deeper into the island’s mysteries.
