Former Capital of the Taurus Nexus
|Corona in the Current Era. The capital of the planet, Albertgrad, is clearly visible as a bright dot on the night side at the bottom left corner, while the University City locates at the center of the concentration of ocean floating habitats at the terminator, just off the western coast of Quark. Corona's auroras, twin orbital rings, and the famous aurora ring are also visible.|

|Psyche, Art, Culture||Metapsychology: Academic Meritocracy|
Culture and Art: Pragmatism, Ubuism
Official Language: Academic Coronese
Languages: Coronese (a systemic, complex constructed language meant to facilitate the conveyance of complex ideas and their relationships, with various dialects, including Academic, Baryonese, Quarkese, Glaran, and Sonatan) is the dominant language, but Hetami (a family of languages derived from the Jovian Creole, widely used on Hera and Hestia) is also widely spoken. Other Iota Network languages are occasionally used, and Solarese is mainly used in Solarist temples and Alemseged.
Timekeeping: Corona and its environs, including Sonata, uses the planet's own calendar, the Corona Calendar. The solar day is 69,842 seconds long, and is divided into 18 'hours', each 3,880 seconds long. 2 leap seconds are added at every midnight. The year is roughly 1031.124 local days long and is not divided into months, but rather referred to by order (Year 256, Day 512, for example). Leap year occurs every roughly 8 years.
|Economics and Infrastructures||Currency: Coronese Tera|
Economic philosophy: Merit-based post-scarcity commons. Land and infrastructure are jointly owned by all with citizen dividends relative to academic performance.
Major Industries: Academic publishing, infotech, tachydidaxy
Military expenditures: Minimal
Megastructures: Two dynamic orbital rings, with space elevators linking them and the planet's surface. The outer ring has the 'aurora ring', a band of transparent screens displaying the aurora texture, hanging down from it.
Angelnetting: Varies from city to city, from virtually none to fully-angelnetted.
|Interstellar Trade and Treaty Relations||Main trading partners: Most important Inner Sphere worlds, some of the empires, especially the NoCoZo.|
Exports: Verified and peer-reviewed data, academic publications, academic appliances, and tachydidaxy technologies
Imports: Data from various projects from throughout the Terragen sphere, data about transapients and archailects, expert systems for local tachydidaxy
It's not every day I get to trade with a higher power, so when the message came through it took me several seconds to process its authenticity. Sirana and I had met that morning to go over some details in our manuscript. I'd gone virtual to join her in her workscape, the topology of the environment mimicked the symbolic logic of our project. To my senses it was a landscape of floating islands, each contained a factual statement, analysis or proposition. Bridges linked the islands to show relevant associations and allowing the veracity of each one, denoted by altitude, to drag its neighbours up or down correspondingly. I'd once peaked into how Sirana viewed it but lacking the sensory modalities for parsing extra spatial dimensions it just served to make me nauseous.
I'd been hiking through some flying lowlands where a dearth of accurate data was threatening to pull an entire section of the archipelago down into clouds non-significance. My exoself announced the message; an S1 entity known as NineStar claimed to have data relevant to our study. E was offering to release it so long as we donated funds to various other Coronese research tribes. I felt Sirana's mental presence, "Trust metrics are high. NineStar has been authenticated by system Archai and there is a record of an entity with that name travelling in the Third Loop Covenant." My point of view shifted to a cluster of well-connected islands representing our work on the TLC. Our project was an attempted reconstruction and sociological analysis of the so-called "Purple Flowering Renaissance"; a century long period that occurred in the Dwellunese orbital band in the Tag system, Tagant cluster.
Data about this period was sparse, partly due to the insular nature of the cluster but mostly due to the blight of 7112a.t. A failed S3 ascension gave rise to a blight that quickly assimilated everything in the Tag system and went on to devastate the cluster over the next few decades (before finally burning out, coincidentally just before impinging on sephirotic territory). The TLC had featured in our studies as a probable location of the Dwellunese diaspora, but no firm evidence of refugees or travelers had been found. NineStar's message claimed that E had encountered a Dwellun in that region and had acquired some memories encompassing the period.
Feeling like I needed some air I shifted perspective back to the Ril. I'd left my body basking on a slipway, the sun was just setting as the city floated further north with the rest of the Lovelace Flotilla. Dangling my feet into the sea I called up information on the groups NineStar wanted us to pay on eir behalf. There was a dizzying array with a range of public abstracts; the contribution of stringed instruments in high pressure environments to mathematic memes, theological analyses of Pith Guru dominance psychoware, sociocultural implications of rumoured archai femtotechnology, to name but a few. I ran a few programs to spot any pattern but as expected no significant link was found in the groups and no reliable predictions could be discerned if they had an increase in funding. Unsurprising if this all played into some transapient's plan.
Sirana's icon appeared before me, "what do you think?" I contemplated for a moment as the last light of the sun fell beneath the horizon. "Confidence is high, trust metrics are significant. Let's do it."
