|House of Thracia|
|Base||Illunii (since Third Age)|
After the fall of Thracia and the death of King Elrond Thracia in the Explosion which ended the Second Age, Prince Celen Thracia settled into the Celenian Forest in Libaterra where he founded the Kingdom of Celenia, named after himself. As the eldest heir to the throne, his family would continue to be called the House of Thracia. Due to disagreements over the rights of succession, Celen's younger brothers Sindaros Thracia and Thylus Thracia left their older brother's side and founded cadet branches known as the House of Sindaros and the House of Thylus in the new nations of Aison and Remon, respectively, at the dawn of the Third Age.
Celen was succeeded by his daughter, Princess Illunia Thracia, who was crowned Queen of Celenia. Over the following centuries, the House of Thracia reigned in Celenia until the kingdom was forced to submit under the rule of the expansionistic human royal family, the House of Locken, after a decisive battle which had led to elves' defeat. The power and influence of the House of Thracia lessened as a result, leading to the rise of nobility such as the House of Barca who more or less ruled as equals with the Queen's weak successor.
In the Fourth Age, Celenia and its ruling house are on the decline after suffering losses in the wars decades prior and the power of the elves diminishing due to the rise of demons in the Andarian Empire.
