The Adeptus Mechanicus prizes all knowledge, going to great lengths to catalogue data of all kinds and seeing even the most inconsequential of trivia as small pieces of holy knowledge. It's this dogmatic imperative that has given rise to one of the youngest yet most important forge worlds of the Forge-Empire of Callamus, Ketavee.

Ketavee is one of those worlds that was founded by order of the Fabricator-General of Callamus to optimise the advantages the Machine God deigned to bless the Forge-Empire with in the Grand Conclave. The then-empty world of Ketavee was given over to the Magi Logis, the analysts and statisticians of the Mechanicus, under whose providential guidance the colonists would transform it into the Forge-Empire's centre of logis prohesysing.

The planet is nearly entirely dedicated to its task of cyber-divination. Data looms and cogitator stacks as tall and wide as Emperor Titans litter gigantic facilities wherein swarms of Logis tech priests collect, process, and organise astronomical reams of raw information. Indeed, the reach of the Katavee project extends far beyond the planet itself or even its solar system; across the entirety of the multi-sector polity of the Forge-Empire, tech priests are obligated to tithe a copy of all the data they collect to Ketavee. This colossal endeavour allows Ketavee to fabricate trillions of prognostications a second, their average quality matched by only a tiny handful of human realms and their quantity matched by none. This has benefited the Forge-Empire of Callamus in countless ways through forecasting events to come, deciphering the state of unclear situations, and uncovering secrets hidden from the lords of Callamus.

Ketavee requires a vast amount of power in order to conduct its prognostications, something that was known even prior to the planet's colonisation. So large was the predicted energy draw that prior to colonisation, the tech priests annihilated the planet's crust just so they could gain direct, maximally efficient access to the planet's energy-rich geothermal interior. Such an action did however make the planet somewhat geologically unstable, greatly increasing the labour and materials required to cushion the logis prophesysing apparatus from the geological activity, which might otherwise interfere with its calculations.

With Ketavee's policy of importing as much data as it can, it is inevitable that some of it will be damaging to mind, machine, spirit, and soul. The scrap code of the Dark Mechanicus is the most obvious and expected of such dangers, but others await. To combat this threat, a million code praetors and hosts of data-sentinels scour imported data packets for these threats, and hexagrammatic logic gates and quarantine auto-catechisms ensure that in the event that anything gets past the planet's guardians, the damage that can be done will be limited.

The solar system Ketavee resides in had been inhabited and developed prior to Ketavee's founding, but upon the Fabricator-General's proclamation they would undergo rapid further development so they could provide for and guard the Oracle World on their own. Three terrestrial worlds serve Ketavee in this manner, as well as a gas giant and its moons.

The vassal planets provide Ketavee with nearly everything it needs, from food, materials, and military aid, but by far their greatest export to their liege world is promethium. Even with Ketavee's geothermal energy production, the planet cannot meet its energy demands on its own. The terrestrial worlds and asteroids are constantly mined for whatever fuel they can provide; fleets of Goliath ships siphon the system's star of sunmatter to supply Ketavee's plasma reactor; the lightning storms that rage across the gas giant's surface are channelled by the motive mastery of the electro-priesthood into Titan-sized batteries, or else are left alone so their antimatter emissions can be captured to fuel some of the Forge-Empire's first antimatter reactors. In both Ketavee itself and on the other worlds, a common punishment a criminal is forced to suffer is to have their bio-electricity drained to just above the point of permanent damage, then after they recover and if the crime warrants additional punishment, they are subjected to the same punishment again, and possibly more times. For the worst crimes, those that in other Mechanicus domains may warrant death or conversion into a servitor, the perpetrators are instead chemically and surgically transformed into bloated, living generatoriums. Kept alive and fattened on a steady stream of high-density nutrient paste, these slave-reactors will spend the rest of their lives providing Ketavee with power, and so benefit the species whose survival they sought to undermine.

*The Convocation of Pythia*

By far the most potent ability of Ketavee is the ability to conduct a grand ritual of enormous magnitude known as the Convocation of Pythia, capable of providing an auspication of the future of such scale and accuracy that it can be matched by only the greatest mortal psykers. Between the necessary preparations and the actual conducting of the ritual, during the latter of which Ketavee cannot conduct its usual logis prophesysing, it takes twelve months to complete. The entirety of the planet's logis prophesysing apparatus is bent to the scrying of a single objective, every iota of quantum computing power and logical deduction and every tiny scrap of data is superimposed into a single quantum superposition of pure knowledge, the enlightening hypersphere of information flooding the Noosphere with rivers of super-dense information concentrate. Alongside this creation of new knowledge, an army of tech priests strain their sensory-recording augmetics to their limits to capture and process the primordial torrent before it can drain into the void. Behind them are reserves who immediately take the place of those who, awestruck at the sheer majesty of the data rush, fall to temptation and experience the complete incineration of their synapses and cognitive circuitry as they deactivate their inload limiters. After the ritual's completion, all that remains is for the newly-created information to be processed and analysed by the forge world.

Unfortunately, the Convocation of Pythia can be conducted only once every sixty-four months because of the cost in energy, labour, lives, and for arcane techno-theological reasons related to the ritual itself. When measured against the sheer strategic boon it provides, it means it cannot be conducted frivolously, lest it be unavailable during an emergency when it's required. As a result, the authority to order its conduction lies not with the Supra-Interpreter\*, but to the Fabricator-General of Callamus themselves.

*Military*

Because of Ketavee's absolute dedication to its purpose, it has very limited space and power for fortifications and defensive emplacements, and cannot produce war materiel of any significant amount. The entirety of the planet's defences are lent by its vassal worlds and from the greater Forge-Empire. Without this aid, the planet would surely have already fallen to one of the multiple attacks it has already suffered. Ketavee has aided during such attacks however, simply not with home-grown military force. The Ketavee System is littered with sensor buoys and augury stations to extract as much raw data as exists within the system and feed it to Ketavee, whose subsequent logis-prophecies will give the system's defenders a vast advantage over their foes.

Even when not under attack, the Ketavee System's military is always active.

To begin with, Ketavee has a compact with the Empire of Ashes, providing them with Ketavee's legions and battle congregations for use in their wars. In exchange, the Empire provides them with an equivalent amount of the data they so desire, and put them in contact with other polities who can provide them with yet more data. So does Ketavee's knowledge base grows, and with it, their ability divine the truth both nearby and beyond in the wider galaxy grows.

As a result of Ketavee's massive, unending thirst for power, the Fulgurites have become the completely dominant faction of Luminen on Ketavee. They are eternally crusading beyond Ketavee's borders, their sacred purpose to seize the free life energy bound by Callamus' enemies and send the stolen animus to Ketavee, where it can be turned to the Omnissiah's holy work. The Fulgurite electropriests have stripped the bioelectricity from hordes of mutants, orks, and Chaos cultists in the course of this holy work, and in the wake of these devotees to the Motive Force, entire cities and ships lay discarded as nought but cold, forever dark tombs.

Ketavee's smallest projection of force, but by far the most important, is the military actions it enacts on the planet itself. Cults and terror cells do occasionally arise--whether from Chaos, Logis clades falling into violent, nihilistic despair from learning too much about the state of the galaxy, or some other reason that drives them to treason--and while hacno-cellular mandatum divisions ensure they cannot immediately compromise too much of Ketavee's functions, they pose a vital risk if left unchecked.
