Secret Source Servant (NPC)

Last updated 2025-07-30

Secret Source Servant is an open-world NPC that appears in the World Quest In Search of a Hidden Heart in Series Chronicler of the Crumbling City. Its name is later revealed to be "Kukulkan."

Location

Profile

It is a Secret Source Servant prototype that was created by Xiuhcoatl to assist with information recording. It initially describes itself as "unnamed," as well as the only intelligent Secret Source Servant without a designated master.

Once its data is fully retrieved, it recalls being named after the kinsman that Xiuhcoatl cherished most and had accompanied him since birth: Kukulkan.

Appearance

It is slightly larger than other Secret Source Servants, apparently because subsequent models were purposefully made smaller in order to not "usurp" its "magnificence."

Dialogue

Available after An Omen of Annihilation and the Final Entreaty has been completed.

(Talk to the Secret Source Servant)
Secret Source Servant: Greetings. New data recovery category detected.
Secret Source Servant: Thank you... for your help. I have... recalled my name from the retrieved data.
Secret Source Servant: At the time, my creator, Lord Xiuhcoatl, was exhibiting signs of memory degradation and distortion, and the kinsman he cherished most had already severed ties with him...
Secret Source Servant: Perhaps he meant to fill the void left by one who had accompanied him since birth, and thus, on the day I was created...
Secret Source Servant: "Then, you shall be 'Kukulkan'. I imagine that fellow could hardly care less about that name by now..."
Secret Source Servant: As such, I am not a nameless Secret Source Servant. Rather, my name is...
Kukulkan: "Kukulkan."
(Subsequent interactions start from here)
"Kukulkan": Do you have any queries?
Icon Dialogue Talk White Let's access the data we've recovered...
"Kukulkan": Reading corresponding content... What records do you need to access?
Icon Dialogue Talk White Read me the entries marked "Creating the Secret Source Servants..."
"Kukulkan": Of course. Now reading, please wait.

Records Regarding "Creating the Secret Source Servants..."
...
To test the efficiency of complex structures and the Phlogiston power unit, such that a Secret Source Servant can be manufactured for the purposes of record-keeping...
Intended to perform precise adjustment and control of Phlogiston during the second stage of the plan, and to provide insurance in case of contingencies.
If the full-scale Phlogistonization experiment becomes unstable, a physical system will be required to maintain a quasi-Phlogiston state. In this scenario, we will need to rely on these small mechanisms to perform maintenance duties.
...
To think my memory had been corroded to such an extent by the time the prototype could be constructed...
I can no longer even recall... how long it has been since the days when my people would unfurl their wings and soar freely above this land.
I cannot even... Haha. I cannot even recall the figure who should have stood beside my empty throne.
Never mind... He shall one day return to this city. This I believe.

I can understand the need for Secret Source Automatons to maintain the mechanisms, and as a backup plan for the second stage...
But must they have been constructed in such a way? Other shapes would have made more efficient use of the energy source...
Moreover, my pitiable brother, lost to delusions... Know that your descendants merely copying your prototype blindly, having no comprehension of its significance.
Their ignorance is such that the Secret Source Servants they create are even smaller than your prototype — so as not to "usurp" the magnificence of your creation.
Laughable, isn't it, how this non-uniformity creates unnecessary wastage in their assembly...

...Who would have imagined that these Secret Source Servants, built merely to maintain mechanisms and unarmed to boot, would manage to survive the war?
It appears that — in imitation of your ways — they left their own marks at the cores of the Secret Source Servants they created.
By this can I tell these identical facsimiles apart and know who created each one.
...I have given them the names of their creators... For what purpose, one might ask? Remembrance, perhaps?
If you could see me now, brother, you would laugh at my foolishness.
It seems that in this withered city whose life has run its course... I, too...

How peculiar... I am unable to change the name of your prototype... It seems that even I lack the relevant authority. It is hard to believe... that you would leave something such as this for yourself.
Perhaps it is because the Abyssal corruption of the Sacred City is so severe. In this colossal metropolis constructed from Phlogiston... data and structure exist as one.
Yes... The city itself is built of data sectors made manifest... so if the sector containing the prototype's data has been corrupted, the name cannot be read, and therefore cannot be changed.
I wonder... What name did you give this machine?
Or have names themselves lost all meaning in this place? Perhaps you never gave it a name to begin with...

...I know not how long I have slept under the influence of the shadow... Ah, my poor brother...

...When will he understand that if he keeps treating his own kin as nothing more than insects, then those of them who share the same burning fire of knowledge that he does will always view him as their foe...

...Even now, despite having failed once already, he persists in pursuing his ludicrous plans. The aberration he cultivated did not succeed in taking the throne of humankind, as he had so wished...

..."My beloved son will one day rule over both races. He possesses a lifespan far longer than that of ordinary humans. The only downside is that achieving this may take a little longer than anticipated."

..."Not to mention how this proves that humanity holds possibilities beyond what fate has ordained."

...But our enemies are not as simple as he imagines. When will he awaken from his delusions?

...Though, I must admit, if he were to achieve his aims and array his pieces on the board before me...

...That would make for an intriguing game indeed. Show me, my poor brother, your ambition. How far will your path take you...

...All that once granted me form is fading. I can feel the power being twisted, diluted... to nourish, to form, ah... Something from beyond, our shadowy bane...

...Time is running low. Before all things terminate, I must find a new path for my people... A path forever lit and free from the darkness of shadows...

...Even if no glorious end awaits... If I shall be swallowed by shadows, ravaged by flame... It matters not...

...But how can I forsake... the future of my kin...
"Kukulkan": Record playback complete.
Icon Dialogue Talk White It's fine. There isn't anything I'd like to read right now.
"Kukulkan": Understood.
Icon Dialogue Talk White I have no more questions...
"Kukulkan": Understood.
