>[!meta-dates] >- **Created:** 2025-05-11 >- **Last updated:** 2025-08-01 >- **Author:** TJ Trewin >[!info] >I'm trying something new with **purely link-based navigation** to explore this world's lore! On larger screen sizes you can also use the graph view to explore. This page serves as an entry point to find hub pages that branch off into specific areas of the world. These act a bit like category folders but better, because one note can be linked to many hubs. 😄 Notes will expand into their own separately linked pages over time, and expect to see [[Placeholder names|literal placeholder names]] here and there. You can still find absolutely all notes within the *Lore* folder, but it's alphabetically sorted. The *Out-of-universe notes* folder contains facts and meta-narrative that I really want to share that the inhabitants of my world may not have discovered or created themselves (like the actual, factual world map, tectonic plates and climate maps nerdery, how magic works, and other stats & figures). As cultures and characters emerge, notes will be updated to include different perspectives and theories on things. 😄 ## Framework & development **Genre:** Fantasy **Subgenres:** not yet defined **Related foundational notes:** - [[Building a world from scratch - tectonics & all]] - [[Yes-no list]] - [[Presentation & narrative perspective#What will I choose for mine?|Thoughts on presentation & narrative perspective]] - [[Thoughts on magic]] - [[Creature design - holding and using items]] - [[Thoughts on sapient species]] ## Groundwork >[!info]- Celestial bodies >I decided against a research deep-dive into astronomy papers for this one. It's not a particular field of interest for me, and it's not a focal point of my fantasy setting. Nevertheless, I enjoy having some plausible numbers to play with, so I used [Artifexian's guide and calculator](https://www.youtube.com/playlist?list=PLduA6tsl3gyiX9fFJHi9qqq4RWx-dIcxO) for this! > >These will come in handy for things later down the line like calendar systems, celestial events, and scientific and cultural beliefs. > >>[!info]- Galaxy >>**Galactic radius:** 31,800 ly >>**Galactic habitable zone:** 14,946-19,080 ly >>**Stellar neighbourhood** >>- **Location:** 16,800 ly >>- **Radius:** 12 ly >>- **Stellar density:** 0.0029 stars/ly³ >> >>>[!info]- Local cluster >>| STAR SYSTEM NAME | SYSTEM TYPE | STAR CLASSES | DISTANCE FROM HOME | COORDINATES (x, y, z) | >>| ---------------- | ----------- | ------------ | ------------------ | --------------------- | >>| Home Star System | Single | F | 0 | (0, 0, 0) | >>| Star System 1 | Binary | MM | 5.28 | (-2.64, -1.95, 4.13) | >>| Star System 2 | Single | L | ==11.87== | (4.39, 11.02, 0.36) | >>| Star System 3 | Single | Y | 8.83 | (-0.62, 7.68, 4.3) | >>| Star System 4 | Binary | MM | 5.37 | (-4.92, -1.96, 0.88) | >>| Star System 5 | Quadruple | MKMK | 11.18 | (-9.37, -6.1, 0.26) | >>| Star System 6 | Single | M | 11.48 | (10.24, -0.32, 5.2) | >>| Star System 7 | Binary | MT | 11.86 | (-3.42, 11.22, -1.75) | >>| Star System 8 | Single | Y | 11.58 | (-3.95, -5.66, 9.3) | >>| Star System 9 | Single | M | 11.84 | (4.22, 7.11, 8.48) | >>| Star System 10 | Single | D | 11.62 | (-1.55, 5.46, 10.13) | >>| Star System 11 | Binary | MM | 8.95 | (-3.21, 8.35, 0.27) | >>| Star System 12 | Binary | TT | 8.81 | (2.02, -7.9, 3.33) | >>| Star System 13 | Triple | MML | 9.80 | (-4.77, -3.13, -7.96) | >>| Star System 14 | Single | D | 10.17 | (-9.08, 4.12, 2.03) | >>| Star System 15 | Binary | ML | 11.34 | (-9.5, 0.45, 6.19) | >>| Star System 16 | Single | G | ==4.98== | (1.48, 3.88, -2.76) | >>>>[!caption] >>>>![[tjtrewin_galaxy-cluster-coordinates_made-in-GeoGebra-org.png|Graph with x, y, and z axis plotting different coloured circles that represent the location of star systems.]] >>>>Single = grey, binary = green, triple = blue, quadruple = purple. >>>>System 2 is the furthest from home, and system 16 is the closest. > >>[!info]- Star >>**Class:** F8.6V (main sequence star) >>**Mass:** 1.105 Msol (solar masses) = 2.19 x 10³⁰ kg >>**Current Age:** 6.314 Gyr (gigayear/billion years) >>**Maximum Age:** 7.408 Gyr >>**Radius:** 1.059 Rsol (solar radii) = 737,196 km >>**Luminosity:** 1.492 Lsol = 5.71136²⁶ W >>**Density:** 0.931 Dsol = 1.311 g/cm³ >>**Temperature:** 6204 K = 5930.85 °C >>**Star Colour:** white >>**Habitable zone:** 1.165 -
