The Yeon Family (연 가문, Yeon Gamun) is one of the 10 Great Families lead by Yeon Hana. Interestingly enough, members of the family do not carry her blood as all of them are born from Ilarde, the "godmother" of the clan.
Like the Ha Family, the Yeon Family is a thoroughly matriarchal family, so males cannot take central roles in either the main house or the branch house of the Family. Thanks to this, the females of the Yeon Family, especially those of the main house, have a tendency to look down on men.
Daughters of the Yeon Family line are born around once every 100 years. Among the several branches of the Yeon Family Yeon Yihwa comes from a very rare family gifted with amazing flame manipulation abilities which can develop abilities that will even put members from the Khun Family to shame. 
They are also the rulers of the 21st Floor. Their members carry a broach that holds a rare jewel referred to as Zygaena's Flower, which grows inside a Zygaena. In order to protect the value of the gem, the Yeon Family control the Zygaena offspring in order to keep the rare statue of this gem.
At some point, the Yeon Family selected the jewel Zygaena's Flower as the crest of the Yeon Family, which can only be found in the body of the Shinheuh Zygaena which is indigenous on the 21st Floor. Because of this, several members of the Yeon Family wear them as hairpins. In order to protect the value of the jewel, the Yeon Family hunts down several offsprings of Ziguenas while classifying it as endangered species on the 21st Floor.
- Yeon Ilarde (Godmother)
