Merfolk

Merfolk are humanoids that inhabit the oceans & swamps & share simliarities to fish & amphibian creatures.

Appearance
Merfolk are very diverse and their appearance usually depends on their environment & living conditions, but most of them share some key features:

Gils: they help them breath underwater in a more efficient way. they can come as small cut like holes on the neck or as big ears on the side of their faces

Webbed feet: this special foot structure helps them swim & move in water better then other creatures.

Geography
Merfolks are all over Rathnir & Eldham, mostly near oceans & or swamps, so they wont be too far away from their ancestors.

Origin
alot of folk stories have different versions on how the merfolk came to be. but the most popular one says that a whale kissed by the gods, laid eggs that gave life to one male & one female merfolk, that later procreated and spread the merfolk all around earth.
