ALPHA CYCLE 0: The thread of creation
At the beginning of everything, there was nothing. A boundless realm of darkness, untouched by form or purpose, inhabited by shapeless, mindless creatures whose very essence was the void itself. These beings, trapped within the infinite expanse, could not fathom a reality beyond their own hollow no-existence. To them, there was no thought, no dream — only the timeless, unchanging, silent nothingness.
But from this void, without warning or cause, there emerged a note. A sound so pure, so absolute, that it rippled through the expanse, shattering the silence of eternity. With it came the light, illuminating the void and revealing a universe yet unmade, a breath of creation that awakened the realm of infinite possibilities.
With it, the celestials were born. Beigns of radiant power and meaning within. Carrying the purpose of the light that had brought them into existance, they wove the heavens, casting stars into the void like scattered jewels. Burning with life, the light of each star spread warmth and magic across the new cosmos.
As the Celestials' symphony grew, they turned their focus to one creation unlike any other — a world where magic would flow like blood through veins, where the threads of reality could twist and reshape themselves and that, unlike the stars, wasn't fixed and eternal. It was raw and untamed, a realm of endless potential, of untamed beauty and possibility.
The Celestials carved rivers and raised mountains, painted skies, and stretched oceans across its surface. They weaved the leylines, threading invisible strokes of power that bound the land, sea, and sky together and all the creatures living within.
And then, having finished their work, they left to watch from a higher plane. For better or for worse, this new world would keep turning, imbued with the magic from above.
Because for as long as magic flows and life endures, this song of creation will echo through the ages.
CURRENTLY IN DEVELOPMENT:
- Basic game systems:
- ~~Dynamic area-limited noise biome assigment system~~ Done
- Algorithm for placement of structures
- Algorithm for placement of streets
- ~~Placement of megastructures (structures that are bigger than the theoretical limit of the vanilla structure system)~~ Done
PLANNED FOR FUTURE CYCLES
- "Old Piltover" base biomes: Featuring a clear Shuriman influence, as this is the part of the city on the Shuriman continent and where most historical connections are seen, but is also the less secure part of the city, where most middle class everymen live, walking the isthmus north to the university and places of work.
- "New Piltover" base biomes: Featuring the more widely known white tall buildings with golden accents and red roofs, where the technology is most advanced and the richest and most influential individuals live.
- Isthmus base biomes: The isthmus itself is now mostly in use for the passage of ships through the sun gates as well as water canalisation from Pilt River to the shuriman part of the city and down below. It can be traversed afoot, altough it is usally well guarded.
- River pilt: This river starts in the northern mountains, and splits various times as it reaches both Zaun's northern chasm and Piltover itself.
- Zaun surface level (Promenade) biomes: Right in the middle of the isthmus one can appreciate the wall that is the mixture of old shuriman buildings with Zaun's neo-industrial architecture. They go down in height as so does the terrain below, once at the same level than the isthmus itself, now suspended in the nowhere between the land routes above and the ship routes below, sorrounded by the water, creating a sort of "natural staircase" in which the luckiest people of Zaun live, being able to reach the isthmus bridge by foot, as well as the lower decks that open to the ocean.
- Structures:
- The Sun Gates (Including its access points and the aqueduct)
- Hex gate tower (As seen in Arcane, maybe next cycle)
- Kiramann mansion (As seen in Arcane, maybe next cycle)
Other features planned for future cycles:
- Zaun entresol level base biomes
- Zaun slum level base biomes
- Firelight hideout (Biome and/or structure)
- Procedural generation of Piltover layouts (Streets and non-structure buildings)
- Piltover university (Structure)
- Lymere's house (Structure)
