Kardia is a country located on the continent of Sephia. It's an island that seems to be mostly covered in forest.
Not much is known about Kardia at this point. It seems to have both magic and technology, but it is unknown to what extent either is present.
There seems to be many travelers in Kardia, as The Highlands Inn was quite full. There were many people of all trades and backgrounds staying at the inn. It can be assumed that Kardia is a diverse country.
