Cymrilians [5e race]

The country of Cymril lies at the center of Seven Kingdoms and its green crystal-spired capital is the greatest city and unofficial capital of the alliance. It's people are descendants of the Phandre, masters of sorceries and rulers of Old Phaedra, until a rebellion instigated by the Orthodoxist faithful. Many Phandre were put to torment, but most of the wizards fled like beetles exposed beneath an upturned stone. In the wilderness they founded Cymril.

The Cymrilians are counted among the Talislantan races of men, so the standard human 5e racial options could be used for them. However, I think something like these variant human subtypes probably fit the Talislantan millieu better. Unless otherwise noted, treated them as human in particulars.

Cymrilian Traits:

Koresians

Typically just called Cymrilians, they are the dominant group in society. They have pale green skin and hair, and golden eyes.

Ability Score Increase: One ability score increases by 1 point.

Magical Society: Gain proficiency in Arcana.

Languages: Koresians can speak, read, and write ancient Archaen.

Tanasians

Tanasians are the exiled descendants of the former Phandre ruling caste and make up less than two percent of the Cymrilian population. Some have been raised in exile by families perhaps yearning to regain their former glory. Others may have gone to live in the wilderness, abandoning what they seen as the folly of their ancestors and political intrigues. Tanasians physically resemble Koresians.

Ability Score Increase: One ability score increases by 1 point.

Skills: Traditionally raised exiles gain proficiency in Arcana, while dissenters gain proficiency in Athletics and Survival

Languages: Traditionally-raised Tanasians speak an additional language, likely one related to their place of exile.

Pharesians

Make up about three percent of Cymrilians. They are voluntary exiles and nonconformists, owing to historical prejudice against the lime green of their skin. Many become itinerant peddlers of talismans and arcane parephenalia.

Ability Score Increase: Wisdom score increases by 1 point.

Skills: Gain proficiency in Perception and one other skill.
