To start I would like to credit @stable cosmos and @sturdy laurel for giving me the inspiration for this idea with their ongoing collaboration in the (absolutely epic) following thread: https://discord.com/channels/393040947006406657/1120394592265719950
IDEA:"Ancient Ones" (AO for short) would be Great Ones with a twist. Instead of an exceptional individual of a living species, an Ancient One would be an individual from a now extinct species that formerly lived in the region occupied by a specific reserve.
**SPAWNS:**Spawning an AO would not be a harvest-based RNG roll like a G1, but progression based for its specific reserve. In effect, it would have a constant passive spawn chance that increases with every mission you complete, outpost you discover, collectible you find, and hunting structure you make the spawn chance increases. The chance would be at its absolute peak when you have fully explored a given map and completed all of its missions.
I know that would be tedious, so in addition to the RNG passive chance an AO could also spawn once you have spent a certain number of total hours playing the game, likely 60 or more. This would also stack across all reserves and trigger the AO spawn on whichever reserve you are on when you pass the play time threshold. Overall, this effectively makes them much more accessible to casual players as it guarantees that they will at least one eventually if they play for long enough.
In addition, AO spawns are hard locked until you reach level 60 (where you are given one guaranteed spawn) to ensure they're restricted to the end game.
AO NUMBERS: I am unsure of a specified maximum, but my idea so far is at least one (preferably two or more) AO species on every reserve. Also, only one individual would spawn at a time.
Due to space constraints I will elaborate further on the mechanics of AOs and my ideas for which AO species should be on which reserves in a series of replies below.
