There lies your destination, but you are yet to begin your journey.
Pack your belongings and get ready, for the sea awaits your arrival.

Synopsis

Difficulty levels
- Calm Seas and Surging Waves are initially available, while Surging Waves +1 and above are unlocked by completing a run in the preceding level (e.g. Surging Waves +8 will be unlocked once the player completed a Surging Waves +7 run).
- The specific handicaps of Surging Waves +1 and above are carried over to every succeeding levels, with those increasing enemies' attributes stacked on top of each other.
- Buff increases the HP and ATK of enemies by the specified percentage on each floor (starting on 1F and increases on subsequent floors), using the following formula:
a = (1 + b)c
(a is the total buff; b is the buff percentage; c is the floor number).- Therefore, in 5F at Surging Waves +15, enemies will have their HP and ATK increased to 210%.
- The secret floor applies the buff at the floor when the player enters it, and do not increase the buff.
- Score is a modifier to the run's final score.

Nodes

Operation Everyone has their weapons drawn. They're definitely not here to negotiate. Self-explanatory.
|
![]() |
Emergency Operation Some violence may well exceed your expectations, a very common occurrence. An ISW-NO operation with various handicaps, similar to that of Challenge Modes, and always awards a Collectible when cleared.
|
![]() |
Dreadful Foe Criminals, ruffians, and the damned... You're in trouble. An operation featuring I.S.-exclusive bosses, which can be distinguished by the ISW-DF code.
|
![]() |
Encounter New friends, old rivals... Strange encounters never age. Only scars stand the test of time. A random event.
|
![]() |
Wish Fulfilled There are many ways of making a wish, but the wish itself is almost always the same thing. Gives a Collectible of the player's choice.
|
![]() |
Safe House Nobody will bother you here, and there's plenty of food and water. No need to be so tense all the time. Gives a free reward of the player's choosing from three of the options listed below:
|
![]() |
Downtime Recreation A little indulgence in life's simpler pleasures goes a long way in fighting the monotonous and the harrowing on your long road ahead. A mini-game where the player spend
![]() |
![]() |
Regional Commissions The long road is unfinished; the only ending you see is a new signpost. An Encounter where the player can accept a Commission from three difficulties which merits various rewards of their choice when completed. For more information, see Regional Commissions.
|
![]() |
Rogue Trader Neither an ally nor an enemy. Some people like to sit on the fence. See Rogue Trader for more information.
|
![]() |
Fortituous Opportunity The lighthouse has fallen. People open their bags, delivering light for each other. Can exchange a Collectible with a different one. Otherwise, the player will receive 4
![]()
|
![]() |
Emergency Dispatch A lantern cannot illuminate without oil, a fincatching boat cannot sail without fuel. Do not underestimate the importance of adequate supplies. Can send off one Operator until after the die roll at the start of next floor, at which the Operator will be automatically promoted (if not already) and suppresses the Rejection they had (if they have one) in addition to receiving some Originium Ingots. Otherwise, the player will receive 3
![]()
|
![]() |
Wander Into Wonderland And thus the bard sings: "Oft are desolate fields and floral gardens neighbors; oft is losing one's way but another adventure." Can enter the secret floor. Otherwise, the player will receive a random Collectible.
|
![]() |
Dense Fog There's something in the mist, but you cannot see anything... The node cannot be identified until they become accessible.
Nodes can only be in this state while the player is hearing the Echoes: Adaptation Call of We Many. |
Floors
![]() 1F – Sunshine Coast
|
The waves pass the steps devoid of footprints, the foam soaking the bricks at the base of the wall. This is a form of clamorous silence, where the land and the sea join in harmony. Unfinished Simulation The wind and waves wrap around your ankles, gently pulling you away from the land and into its embrace. |
![]() 2F – Offshore Island
|
This island is not far from shore, but nobody knows how it came to be. The ocean wind pushes ajar the doors of the buildings here, light and shadow interweaving... Go on–enter, and take a look. Unfinished Simulation A spark of light inside a building is the best way to lure in visitors. As long as they take the bait, this isolated island far from civilization will still be able to feast. |
![]() 3F – Raging Billows
|
The sky darkens, those dangerously beautiful tides shimmering as they gradually become clearer. They quietly spread towards the mouth of the cave on the island, right at our feet. Unfinished Simulation The water rises, sealing the entrance to the cave. The tide stretches its limbs, grabbing onto its prey. |
![]() 4F – Secret Hotbed
|
Deeper inside the cave, the moss creeping along the rock walls begins to proliferate wildly, covering the entire surface. Life does not require the light of day to thrive. Unfinished Simulation In places devoid of light, survival is the sole impetus of life. Should you fail to come to terms with this reality, then you will be completely devoured by the life here. |
![]() 5F – Sacrosanct Cave
|
The ocean current abruptly veers here, the sound of the rushing tide resembling that of crying. They seem to have been deliberately avoiding this place... Apparently, nature is not the only inhabitant here. Unfinished Simulation A true predator never needs to take action. The invisible helping hand of curiosity will naturally push the next meal into its mouth. |
![]() 6F – Deep Sea Woodland
|
The sound of plants breathing resonates at the same frequency, and countless motes of fluorescent light rise amidst the forest like a galaxy hanging upside-down on the ocean floor. What kind of soil could give rise to such a wondrous grove? Unfinished Simulation You applaud nature, but nature only finds you to be noisy. Nevertheless, it will still take you in, whether you agree to it or not. |
![]() Secret – Indigo Cradle
|
Time. Time. Time is their sustenance. Across lengths of time immeasurable, the cerulean branches continue to linger and grow, and thus does life sway and unfurl. This place has everything, and nurtures all. Unfinished Simulation Everything around you is a vibrant cerulean, and you can no longer find any way to escape. The age of plants is boundless, and you have reached the end of this futile search. |

Result
When a Caerula Arbor run ends, the ending will be played if the run is completed; if the run fails, the "Unfinished Simulation" message is shown instead.
Afterwards, the Data Rollback (which can be skipped and viewed again from the result screen) will be shown, which highlights the player's actions throughout the run as follows:
- Path of Light: The player's Light upon entering each floor.
- Rejection and Enlightenment: The Rejection afflicted on Operator(s) and Enlightenment(s) obtained by the player.
- Monitor Fate: How many times the player have rolled the die and how much die rolls that gives off each of the five possible results, and the instance when the player rolls the highest and lowest number.
- Important Points: Will only appear if the player had done the following:
- Making decisions in certain Encounters.
- Entered the secret floor.
- Looted the Rogue Trader, showing the total value of the looted wares.
- Entered the "Buy Now, Print Now" Downtime Recreation, showing the amount of
Originium Ingot spent there.
- Obtained
Breath of the Tide, showing the amount of operations where the Tide-Hunt Knight appears.
After the Data Rollback ends with the message "Rollback Complete", the player will be taken into the result screen, which shows the summary of the run as follows:
“ | You, Dr. {nickname} used the {Squad} and spent xx hrs xx min xx sec starting on yyyy/mm/dd hrs:min:sec Witnessed the {ending}1/Ended your journey at {floor name}2 | ” |
- 1 If the run is completed
- 2 If the run fails
The result screen also shows the following:
- A flavor text that varies depending on the run's outcome, after the summary above.
- A list of Operators the player have recruited and promoted during the run.
- A list of Collectibles and Enlightenments + the Rejection the player have obtained during the run.
