Humanoids

Races are more prevalent on the surface based on how they originated—elves are numerous, coming from Feya which is just below the Material Plane. Genasi, dragonborn, and etc. are more rare as they came from further down. However, aasimar are a bit more numerous as they were called from below to fight in the war long ago. Tieflings, which came from the Umbra, are also numerous on the surface but tend to condense into small areas rather than spread out. Thus, it is still unusual to see one outside a large city.

HUMANS
Originated on the Material Plane.

DWARVES
Dwarves originated on the Material Plane, but they became slightly more magical by their presence to magical stones inside the mountains. They are related distantly, by genetics, to gnomes, which tend to live in mountain valleys or on islands.

GOBINOIDS
Goblinoids come from the corrupted ancestors to dwarves (hobgoblin) and gnomes (goblin). Gnomes have welcomed some goblins/hobgoblins into their worlds, which has proven to be a good idea. You can tell a gnomish goblin by their unkempt hair (gnomes prefer it messy, as not focusing on appearance and focusing on work is culturally expected) and functional clothing.


 * Gnomes and goblins have tails and large, round ears. Goblin tails are longer. Both have big, wholly black eyes.

ORCS
Orcs are a kind of elf, a sub-race that was corrupted during the Blighted Ages, shortening their lifespans from around 700 to around 450. They are more or less the same as PHB orcs, but with more capacity for creating civilization and having empathy. There are sub-races of orcs, and some are known as less violent than others.

DROW
There are two kinds of drow; ones that live in the light (and lose some negatives/positives of their race) and ones that live in the hollowed mountains of Lacidere's corpse. Underground drow are identifiable by longer, bat-like ears, sharpened teeth, and longer limbs.
