Flames Reach

Flames Reach is an inhospitable volcanic death world located in the Segmentum Tempestus. Despite it's deadly environment, there are small pockets of life located near small terraformed zones that are able to sustain life. This deadly world is home to the newly created Ultima Founding Burning Fate Space Marine Chapter that consists entirely of all Primaris Space Marines.

Background
The death world of Flames Reach is a highly volcanic planet whose oceans are entirely made out of lava and magma. Most of the ground is made out of dark grey stone. The planet is mostly barren but does contain small pockets of animals and tribes that live near terraformed zones made for limited survival until another planet was habitable.

The world houses a number of constructs creatures that act as its fauna. These Constructs are known for being docile to humans and being used to plow the habitable land and defend it from the one in a million rogue construct that is out for bloodshed.

Fortress-Monastery
The Fortress-Monastery, nicknamed the ' Castle Of Ashes ', is located in the largest volcano upon the death world of Flames Reach. For recruits to reach the monastery they have to walk on a thinly-carved path that leads into the volcano and watch out for bursts of magma and predators that live near, and within it.

Inside the monastery there is the Reclusium Librarium and Apothecarion where the specialists of the Chapter gather to hold discussions about anything that needs to be addressed as soon as possible. In a lower level the Technicarium is located where vehicles and wargear are also stored. There weapons and parts are reforged using the lava which is also used to power everything aboard.

The defenses are mostly focused against heat and blunt type damage. Having reinforced plating made out of heat resistant material with a thin coating of blunt resistant steel. The weapon platforms are evenly spread across the crater. These firing molten iron and pure streams of magma.
