First of my interpretations of Pre-Heresy Ultramar. Hope these are interesting. These are only intended to give me some ideas, so if you've got any corrections, suggestions or additions, please feel free to post!CalthCalth is part of Ultramar, the Ultramarines Empire, and one of its most productive worlds. It is a verdant and fairly populous world, its surface covered in rich and varied terrain. It has an overall mild climate a few degrees cooler than Ancient Terra, and a gravity slightly higher owing to its larger mass. Owing to a particularly stable orbit, seasonal changes in weather are slight, and crops and agriculture are grown steadily throughout the year.

The inhabitants are reknowned for their parsimony and level-headedness, and operated in much the same way for thousands of years before their rediscovery by the Imperium. Slightly shorter than galactic average, and typically endomorphic in build, Calthans exhibit moderate genetic diversity. Most inhabitants have dark, almost black, irises; and have a ruddy, olive skintone. Dark, tightly-curled hair is the norm, though the planet has alos produced an extremely unusual genotype with violet-blue eyes and near-white hair. Beyond this, incidences of mutation are low, and psychic phenomena are virtually unknown.

Roughly seventy per cent of the planet's denizens live in secondary agrarian settlements, while the remaining urbanites drive scientific research; a profession for which many show a particular aptitude. Government has varied, but the great Techniclans dominated pre-Imperial leadership, and their respect for machinery and natural resourcefulness, inventiveness and industry tends to make for excellent recruits for Techmarine aspirants.
The planet is also known for its orbital shipyards, which provide the craft used by the Ultramarines, as well as civil and military craft for wider use in the Imperium. The Techniclans of Calth make excellent and advanced weaponry, their scientific drive matched only by the outputs of their manufactories. Their weapons, armour and equipment make up much of the XIII Legion's materiel for the Great Crusade.

Calthan Ultramarines tend to exhibit the same conservatism as their gene-folk, and rarely progress to high leadership positions, unlike the more creative and strategically-minded Iaxians, or the resourceful inhabitants of Parmenio and Espandor.
Nevertheless, numerous excellent line officers and infantrymen have been drawn from Calth, and its soldiery are known for their stubbornness and faith in the Imperial Truth.

I'm thinking of Calth as a Mediterranean-type climate, which'll let me play around with some Roman skintones.
