Introduction
“Once we are connected, wisdom shall springeth forth.”
Xaihi is from the Cabal of Tranquility, a research order dispatched from Laterano to Talos-II for technical study. As a Sessionite, she believes computation and linguistic analysis pave the way to Veritas.
She is better with machines than with people. Her talent in information technology is undeniable — even to the Abbess of the Great Monastery in the Cabal of Tranquility. So despite her "unauthorized" upgrade to the dome of the Cathedralis triggering a cascade of accidents, the Abbess still sincerely recommended her to Endfield Industries, hoping she could find a stage worthy of her genius.
Now, Xaihi works aboard Dijiang on information engineering tasks such as Protorig Network construction and system integration. Her unique insights into the Originium Network, combined with the deep knowledge she carries from the Cabal, ensure her place as an indispensable member of Endfield.
“O Knowledge most ancient, lead us not into temptation but deliver us from the codes of malice... I am Xaihi, Endministrator. May you be enlightened.”

Operator Promotion 1
Behold, the benevolence of the Law manifested... Ah, and with it flows the trust of the Endministrator! Is it not righteous to give thanks unto thee?
Operator Promotion 2
The Law watches over and preserves the meek, but not the learned, wise, nor rich. Though elevated by such glory, I remain humble and thankful to thee.
Operator Promotion 3
Everything is as clear and distinct as the veins of Originium. This promotion aligns with the projected outcome. Huh? Sh-shake hands? I ... I am not very good at that...
Operator Promotion 4
I once restructured the codec dome of the Cathedralis to enhance its working efficiency. Yet, unanticipated resonances occurred as the ancient algorithm processed the data flow. The result was ... complicated. And yet, what once exiled one from their homeland ... has become a source of grace here at Endfield. Perhaps this is what the Law wished to reveal to me!
Operator Reporting for Duty

Contemplation... Computation... Utterance... Abandonment.
Standing by 2
I offer today's dialogue and contemplation to your terminal, in reverence...
Assigning to Facility
Let thy commands be fulfilled. O Endministrator, through service, our path is revealed.
Greeting 1
May peace and safety be with you.
Greeting 2
Endministrator, you appear once again in my calculated result.
Dijiang Idle Chatter 1
Validating data, analyzing syntax, generating results... Greetings, Endministrator.
Dijiang Idle Chatter 2
I have received your signal, Endministrator. I am in the process of interpreting its meaning. Please wait...
Dijiang Idle Chatter 3
Ah ... I find myself preferring the presence of machines over the company of humans. While human pulses are erratic and immeasurable, machines breathe in a consistent and logical pattern.
Dijiang Idle Chatter 4
My terminal registered more than fifty errors within the past ten milliseconds. But set your mind at ease, for I have set our communication as top priority. Hmm? My evaluations for Dijiang's overall performance...? I would say, despite a myriad of issues, the vessel has continued to endure her tribulations with grace, as though she is ... suffering for someone else.
Dijiang Idle Chatter 5
As the Law permits, so we act: Paradise shall be restored unto this world. Whosoever paveth the path, shall cross the forlorn wildlands and attain bliss. For Veritas layeth hidden in enigmas, that the lost may no longer wander, but walk with the Noble Ones, sharing in an eternal purpose.
Dijiang Idle Chatter 6
In the eyes of my fellow operators, you are a leader from the past, a noble being in the present, and an Originium sapling maturing toward the future. Yet within the depths of the Protorig Network, I beheld a different you... All I can do is pray — that our signifier and the signified may one day become one. May you walk in blessing, Endministrator.
Offering Gifts
Endministrator, may I interrupt your processing for a moment? I ... I would like to offer a token of appreciation for all the boosts you have brought me. Oh ... you have noticed nothing at all? Phew, I'm so relieved...
Accepting Gifts
This is an indicator! Oh, please forgive my lapse in decorum... Veritas acknowledges your efforts.
Trust Dialog 1
The Cabal shares their knowledge and fate with you, Endministrator.
Trust Dialog 2
All my suggestions prove practical and useful...? No, I do not follow the path of pragmatism... The Abbess cautioned us that, here on Talos-II, we must make our faith yield more tangible and practical results. The abundance of Laterano is a distant memory here. Only our interconnection binds us now.
Trust Dialog 3
After all this time together, I feel I've grown closer to the Endministrator. Now seems an appropriate time to show warmth, trust, and goodwill... Ah, the Endministrator is coming this way. Quickly, Xaihi, execute a gesture of friendliness... Ummm — Endministrator, would you like to join me for morning prayer?
Trust Dialog 4
Please pardon me, Endministrator... Before I make inevitable contact with you, potential static buildup must be first discharged from my fingers... Oh? Do you not fear such things? But ... these tiny miscreants would secretly cling to one's hands ... and sting you when you least expect it ... like this.
Trust Dialog 5
For years within the Cathedralis, I immersed myself in study, never pondering how the fruits of our good work could enlighten Talos-II. Yet, the Law's revelations brought me to your presence, and a new world has since emerged in my sight. One by one, the ancient, tranquil words suddenly came to pass ... and now I fully understand their teachings, Endministrator.
Chat 1
Endministrator, we Sessionites interpret the Law by viewing language as a symbol. By continuously shattering old symbol combinations to create new ones, we draw ever closer to the domain of eternity. This behavior mirrors that of the Shatterus — the entity enshrined behind the sacred statue of the Cathedralis.
Chat 2
Dijiang keeps reminding me of the Cathedralis. However, we do not remain there always. Congregations only occur to resolve moments of schism. When this happens, my brethren and sisters from every corner of Talos-II will return to the place. Hmm? How is the Cathedralis kept safe? If it were ever to come under assault... Hmm, I believe it can be its own guardian.
Chat 3
Never have we stood so far from Veritas, for it has departed from the place we called home. Never have we stood so near to Veritas, for now we have knocked upon its waiting door.
Chat 4
Racing? On foot? Boxing? With fists? And you wish to see me in the sports festival?! I'm afraid ... I must refuse. The only "physical motion" I approve of ... is the magnitude of periodic changes, made by electrons within an oscillator circuit. I could never bring myself to compete against my brethren and sisters! No ... I am not seeking an excuse. I-I must now return to the mainframe room. Immediately.
Chat 5
Yes, there are many Sarkaz like me within the Cabal. Some were even entrusted with relics once wielded by Gun-Knights. Indeed, I have studied the scriptures of the Cabal. I know that, back on Terra, the Sarkaz were in fierce conflict with many other races. However, when the First Aggeloi War ended, an unprecedented miracle of unity descended upon us: Every soul embraced their brethren and sisters, and every pair of lips sang in the same tongue.
Topic: Aggelos
The relationship between the Law and the Aggeloi overrunning Talos-II, is one of the primary subjects the Cabal seeks to interpret.
Topic: Shatterus
There is an Aggelos reminiscent of the Triaggelos, nestled behind the sacred statue in the Cathedralis. We secretly call it Shatterus when outside the hours of liturgy. This construct was seized by Abbess Mumu during the First Aggeloi War. The Abbess encourages us to observe Shatterus and reflect, for the Law's teachings might be found in the enemy. Shatterus presents both a near-accurate approximation, and a formed conclusion yet to be interpreted.
Topic: Three branches of the Cabal
The Cabal now consists of three branches: the Sessionites, the Veritarites, and the Resurgonites. I myself belong to the Sessionites. We believe that computation and linguistic analysis form the avenue to bliss. The Resurgonites, scattered across Talos-II, are armed zealots eager to delve into the ruins of the ancient civilization. The Veritarites concern themselves above all with matters of heart and soul. They study sculptures, create handwritten copies, and guide lost souls home.
