Ekaterina or Ekats

The Ekaterina Branch is one of the five branches of the Cahill family. They are more commonly known, and called, the Ekats for short. The Ekaterina was named after, and founded, by Katherine Cahill, the second child of Gideon and Olivia Cahill.

Pronounciation - Ee - Cat- Er-Ee-Nah


The Ekaterina Branch was founded by Katherine Cahill. The branch's main enemy is the Tomas Branch because Katherine stole one from her brother Thomas, founder of the Tomas branch. Because of this, Thomas swore to take revenge on her. With the compass in her hands now, Katherine moved to an unknown, far-off land, presumably Egypt, as she was a fascinated with Egyptology being an Egyptologist herself.


The Ekaterina's mascot is the Dragon, because the dragon is a mythological creature that appears in countless forms, thus representing and symbolizing the Ekat's creativeness, intelligence, and inventiveness, as well as their willingness to destroy anyone or anything in their path.


The Ekaterina crest is a shield in the shape of a square with jutted, or gradually-pointed tips at the top and bottom of the shield. The Ekat crest, and official color, is yellow or a gradiance of yellow and orange. In the center of the crest is a white dragon; two legs, two wings, a curled and barbed tail, and a head facing left with it's mouth open, exposing a breathe of fire. The dragon is shown to be in flight. The much simpler crest is the same, except only the head of the dragon is shown. As with all of the other Cahill family crests, there is a scroll at the bottom that reads: "EKATERINA".


Ekaterinas are known to be clever and inventive, and the most famous scientists and inventors were Ekats. Ekaterinas excel in engineering, math and patterns, and the sciences. Generally speaking, Ekaterinas are known as the most intelligent of the four Cahill branches, with a brilliant and creative mind. Though not as dangerous as the Lucians, Ekaterinas have been known to commit murder. The Ekaterinas killed the Lucians super-spy Sidney George Reilly. The Ekats seems to think of how their founder would react to their actions more than the other branches, by always saying things like "Katherine would be proud" or "It's time to make Katherine proud".
