I keep losing these diagrams regarding oxidising elements on Tenz' surface so I decided to create something more permanent and detailed this time, and make sure I won't lose it.

Continental configuration of Taya Eõazo (astronomical name; other names include Tenzali, Tensal, Tenz) and cratons (large middle outline is the early continent, and white circles are the cratons) some 400 million years before Midana. This was when Amadaska bloated into a red giant, melting away the thick layers of surface nitrogen and methane ices. This also released oxygen and fluorine but they were quickly absorbed by surface iron in the soil, removing these elements from Tenzali's newfound atmosphere.

Note that at this time the realm was already 10 billion years old and life first arose in subsurface oceans, at a time where Taya was still in a stable orbit around its parent realm, Eonnaya (I don't care about the distinction between planets and moons). Also, a major craton, and continent, is being omitted as I still have to decide on its exact shape, although I don't plan to.

Left: position of landmasses when Tenzali started to warm up. The continents are pictured as they look like during the Midana era, not how they actually were back then.

Middle: rough and inaccurate drawing demonstrating how the continent would have looked like (the silhouette both in the middle, and its smaller version in the lower right corner), along with the outline of modern continents and the position of many cratons (white circles), some of which weren't above sea level.

Right: continental configuration just after the Midana era.

Quick facts about Tenzali:
~6,35% larger than Earth
~10 Moons more massive
Atmosphere is 15 times as massive as Earth's and 22 times denser; it's composed of Nitrogen (89%), Methane (9,6%), Hydrogen (0,80%), Ethane and Propane (0,5%) and tholins.
Average global temperature is -60 Celsius
Despite its size, Earth still has more land area than Tenzali, although Tenzali's ammonia-hydrocarbon oceans can be as deep as 22 km, averaging 12 or so kilometres.
