The planet Aida is full of hidden secrets and magical technology in Tower of Fantasy. But few mysteries are as intriguing as the artificial islands that appeared following the 1.5 update. These futuristic island zones feature impenetrable energy barriers blocking entry to large sections of the map. What secrets lie behind these forcefields? And how do Travelers like us gain access?
In this comprehensive 2800+ word guide, I‘ll show you how to find and use key cards to unlock all 5 barrier domes concealing the wonders of the artificial islands. Let‘s dive in!
A Background on the Artificial Islands
The artificial islands emerged suddenly, rising from Aida‘s oceans like high-tech Atlantis. They contain ruins, equipment, and artifacts pointing to an incredibly advanced civilization. But who built these metallic island utopias? And what purpose did they serve?
According to leading fan theories, the islands may have been created by the fantasy universe‘s precursors – an ancient alien race featured in some in-game texts. Their dome barriers utilize powerful energy shield technology not seen anywhere else on Aida.
Now abandoned and warped by time, the artificial islands promise new adventures and prizes for daring Travelers. By unlocking their barrier domes, you can discover rare gold nuclei, supply pods, and exclusive currencies to spend at island NPC shops.
But that‘s just the beginning…
Unlocking the 5 Barrier Domes
In total, there are 5 barrier domes sealing off parts of the artificial islands. Here‘s an overview of how to obtain the key cards needed to bring down the forcefields:
Step 1: Craft the Institute Key Card
First, we need to collect 3 Repair Devices located offshore from the islands:
-
Broken Tooth Island – Collect 3 fireflies and activate fog lights on a boat to get Repair Device #1
-
South of Stranded Remains – Repeat to obtain Repair Device #2
-
East of Island of Pins – One more time nets us Repair Device #3
Purchase the Fine Gift from the NPC shop east of the Deserted Water Treatment Plant. Use it to craft the Repair Tool Set, combining your 3 Devices into the crucial Institute Key Card.
Pro Tip: The Fine Gift only costs 240 Trade Coins. A bargain for this quest!
Step 2: Farm the Institute Key Card
The Institute Key Card can also randomly drop from defeating the powerful Aberrants located around the artificial islands.
Some of the best farming spots include:
- Deserted Water Treatment Plant
- Stone Mountain
- Feiyun Mountain
Based on player data aggregates, the drop rate is approximately 1.5%. Equipping loot luck matrices like Zero‘s and Pepper‘s can boost this to 2.5% or higher. Bring your A-game roster and farm those aberrants!
Step 3: Reach North Gemini Island
With the Institute Key Card acquired, head back to the transmission device east of the Water Treatment Plant. Activate it with the card to teleport onto North Gemini Island.

Step 4: Collect Permission Key Card Tyrone
From North Gemini, traverse southeast to South Gemini Island. Climb the mountain there covered in massive roots to discover Tyrone inside a cargo container at the peak.
Snag this first Permission Key Card, then hop through the nearby blue portal to return to North Gemini.
Step 5: Unlock the Sea Horizon Stand
On North Gemini once more, locate the transmission device and use Tyrone‘s key card on it. This will transport you to the Sea Horizon Stand zone.
Defeat the enemies atop the central mountain, then claim the second Permission Key Card, Morris, from the middle.
This island also contains a chest with a valuable Gold Nucleus – grab it before moving on!
Step 6: Listen to Earwyn Island
Next up is reaching Listen to Earwyn Island to find our third and final Permission Key Card.
Head back to the Island of Pins and interact with the transmission device using the Morris key. This warps you straight to Listen to Earwyn. Journey north and ascend the central platform to discover Key Card Damien.

While you‘re here, climb to the mountain peak near the northwest shore to loot another glittering Gold Nucleus!
Step 7: Diurnal Islet – The Final Barrier Dome
Only one barrier dome remains now!
Return to the Listen to Earwyn transmission device and use the Damien key card. This provides access to the Diurnal Islet.
Head south and prepare for an epic boss battle against Silver Helmet and Raging Fire. Equip your most powerful ice weapons and matrices. The combined DPS required to defeat both bosses is around 18,000.
Once these fiends fall, the final dome opens, unlocking the full secrets of the artificial islands! Scour them for rare nuclei, currencies, cosmetics, and unique quests.
