Ra

Ra is the fifth Celestial, unlocked by fully completing all of V's Achievements. They bring back mechanics from older Celestials in a stronger way, by using their memories. Over time, you'll unlock the previous four Celestials within Ra, with each Celestial offering additional upgrades related to their original themes.
== Ra's Memory ==
Each previous Celestial within Ra gains levels by using memories, which are generated passively over time from Memory Chunks. Memory Chunks can only be gained by entering Ra's Reality, but inside of the Reality, Chunks will be generated passively based on certain resource totals. If you are storing real time, you will not gain any Chunks inside of Ra's Reality, but Memories will still be generated normally. Having a total of 20 levels across all Celestials unlocks Remembrance, which allows you to choose a particular Celestial to gain more chunks while inside of Ra's Reality. Whichever Celestial has Remembrance will get ×5 Memory Chunk gain. The other Celestials will cut the Memory Chunk gain by half. Ra won't directly unlock the next Celestial.
When you are in Ra Celestial, You will be capped at 4 Dimension Boosts and Tickspeed effect will be fixed at x1.125 (meaning Galaxies will have no effect)
Memory Chunks Base production:
* Teresa: 4*\left(\frac{\log_{10}(EP)}{10^4}\right)^3 (EP = Eternity Points)
* Effarig: 4*RS^{0.1}(RS = pending Relic Shards)
* Nameless Ones: 4*\left(\frac{\log_{10}(TS)}{3.5*10^5}\right)^2(TS = Time Shards)
* V: 4*\left(\frac{\log_{10}(IP)}{10^7}\right)^{1.5}(IP = Infinity Power)
== Unlockables ==
Teresa unlocks the ability to charge your Infinity Upgrades, making them much stronger. They also improve your Glyph effects once you reach certain thresholds in Glyph sacrifice value.
At level 2, Effarig unlocks a new mechanic called Glyph Alchemy and later on also makes Effarig Glyphs stronger while gradually removing almost all random elements of Glyph generation. Glyph Alchemy also has its own How To Play entry.
The Nameless Ones unlocks additional mechanics related to charging the Black Holes, as well as making them significantly stronger.
V unlocks Triad Studies, which are new studies near the bottom of the tree which cost Space Theorems. Each Triad Study requires you to also have the three nearby studies as well in order to purchase them. They also unlock a smaller set of more difficult V-Achievements to complete for additional Space Theorems.
== Upgrades ==
Memories can be spent on three things - an increase to Memory Chunk gain, an increase to Memory gain, and leveling up the Celestial. You start Ra with only Teresa unlocked and each successive Celestial is unlocked by reaching level 8 with the previous Celestial. Levels are capped at 25.
