A World of Hell
The Tartarean Eon
On the surface, the Tartarean Eon is filled with violent volcanism and is met with a constant bombardment of asteroids raining across it's atmosphere and clashing into the countless oceans of lava and shifting tectonics.
Tartarean Lava Oceans
-Oreosaurs
The surface is constantly met by clashing asteroids and comets in a period called "The Early Heavy Bombardment." The crust on the young planet would be unstable and mostly comprised of basaltic proto-continents that rise and fall beneath the waves of lava. Frequent and intense planetary resurfacing was caused by intense volcanism and immense asteroid impacts.
Zircon Mineral Rendition Drawn by AdaFromHellada
Rocks from the Tartarean Eon are rare to find on Azula 155B due to the young planet reaching extreme temperatures as well as being constantly bombarded by impacts alongside having a molten surface which prevented the formation of stable solid rocks. The only rocks that did survive came from outer space, such as meteorites and rocks from the formation of Orion and Mai. The few rocks that were able to survive the Tartarean were hard Zircon-like minerals that managed to withstand the hellscape of the planet.

Heavy elements like iron and nickel fell towards the center of the planet, forming into the core, while lighter elements like gases migrated towards the surface and escaped through many fissures.
A Violent World
-Oreosaurs
In the beginning, there were no continents, no tectonic plates, no life, no oceans, not even an atmosphere, there was only hell.
everything changed at around 100 million years since formation when the unstable binary system of Azula and Persephone collapsed. Due to the way Persephone orbited around Azula - that being in a very elliptical pattern - she got dangerously close to her Roche limit, both simultaneously being torn apart and clashing into Azula 155B. The debris from this catastrophic event fell down to Azula 155B, while others remained in orbit, with few being slingshotted. Those that remained in orbit cluttered up and gave birth to Orion, while those that were thrown across the solar system created Mai.

Near the end of the Tartarean Eon, Azula 155B has pretty much cooled down from its molten state. It is now a landscape of hills, valleys, rocks, and lakes of nearly dried lava.
Although the surface is cooling, it is also met with immense heat, poisonous gases and solar radiation. By the end - Orion has relatively cooled down and the bright molten rock that stared down from the sky shifted down to a dormant, grey-pale state, however, Orion hasn't completely cooled down as there are still pockets of erupting lava trenches accompanied by a thin primitive atmosphere. Orion looks as it is 3 times as wide as in the present day due to him being closer than it is today. Orion also doesn't have any scars - no crater marks - due to him still being young, making him look clean and smooth.
On Azula 155B, the surface is lifted with a common igneous rock called basalt which is when lava cools down on the surface of the planet. During the present day, original Tartarean rocks are practically non-existent thanks to the rock cycle. The surface on the young planet was mainly comprised of igneous rocks during the Tartarean Eon.

Days during the Tartarean goes by faster than it does today because the planet is rotating at a much faster rate than it would in millions of years.
The lithosphere is growing more stable with a solid crust of rocks cooling and hardening. The hydrosphere of water is forming from early oceans to lakes where the first organic molecules will soon form to the rain clouds in the sky. The atmosphere is still toxic, but it was creating a stable environment for the future.

Ultimately, during the end of the Tartrean Eon, there was a Late Heavy Bombardment which brought water via comets and asteroids to Orion and Azula in the masses. The Late Heavy Bombardment was also the cause for the many craters and scars left on Orion from this period of time. The comets that fell across Azula melted and left behind gasses - most comprised of water vapor which eventually complied in the early atmosphere and fell as the first droplets of rain to hit Azula 155B. Soon enough, one by one, comet after asteroid, Azula's oceans were filled with water, covering all over her surface. As the oceans filled and the planet cooled, water vapor in the atmosphere condensed to formed into the first clouds to roam across the sky. Other gasses were also forming such as sulfur, carbon dioxide, neon, nitrogen, and ammonia which helped form the first atmosphere. The sky was a strange orange with a yellow hazy color and there was no oxygen anywhere in Azula's atmosphere yet, however, Azula now had a protective shield against UV radiation to allow it to maintain a constant temperature.
