I intentionally left the biomes that correspond to map colors fairly vague with the hope that people would have more creative license to describe their surroundings. I drew that map initially with four different colors that would correspond to the main biome classes on Ember, and from there modified the colors here and there to give the impression of multiple types of sub-biomes.

There are four major biome classes on Ember excluding the polar icecaps. The reddish-pink regions are known as the painted savannas - a class of environments dominated by a reddish moss/lichen-esque ground cover that serves as the producer base. There are occasional stands of larger plantlike organisms, things that look more like a giant coral growth than a proper tree. This biome dominates the lowlands of the south that were once the seabed of Ember's oceans which have long since disappeared, and as such is one of the wetter biomes. Alien are numerous and diverse here.

To the west of the cluster of lakes is a series of deserts that were once a shallow spot in Ember's oceans. Due to its higher elevation, water drains off this region into the lakes and underground aquifers of the painted savannas. These are a mix of your standard erg desert interspersed with salt deserts and salares. Extremophile aliens adapted to a very difficult environment here.

The previous two biome families can be considered lowland environments, whereas the next two are characteristic of Ember's northern uplands - which are simply the continental shelves of what were once Ember's two major landmasses. The southern, yellowish-brown areas are a semi-arid region dominated by dense scrub. What water exists here drains into a network of rivers and ephemeral arroyos that become deep canyons that flow outward to the low-lying regions. This region is inspired by the Brazilian Caatinga on Earth. The wildlife here are generally not vast herds of megafauna like those in the painted savannas, but rather smaller, solitary creatures that are better suited to negotiating the forests of thorny coral-cactus growth.

In the northern latitudes the upland regions are wetter, and the producer base lifeforms here have evolved into organisms more reminiscent of the trees of Earth. There is more rainfall in these latitudes due to the storm systems that slide southward from the tempestuous polar latitudes. Rainforest environments are likely to be found here.

This is not meant to be an exhaustive explanation of Ember's biomes, but an idea of what to expect based upon map coloration. These descriptions are not meant to be definitive, but to give the player something to build off of in describing their surroundings.
