The Dacian Draco [draˈko] was the standard and ensign of troops of the ancient Eastern European Dacian people, which can be seen in the hands of the soldiers of Decebalus in several scenes depicted on Trajan's Column in Rome, Italy. It has the form of a dragon with open wolf-like jaws containing several metal tongues. The hollow dragon's head was mounted on a pole with a fabric tube affixed at the rear. In use, the draco was held up into the wind, or above the head of a horseman, where it filled with air and gave the impression it was alive while making a shrill sound as the wind passed through its strips of material.

Draco (Latin) and Drakon (Greek) mean "serpent", "dragon". The root of these words means “to watch” or “to guard with a sharp eye”. Apparently, it is a derivative of Greek drakōn "gazing" .

The origin of the standard is unknown and still a matter of dispute among scholars. A specific and certain origin is still difficult to be determined. Dacian, Thracian, Scythian, Sarmatian or Parthian origins have been proposed in dedicated historiography. According to Lucreţiu Mihăilescu-Bîrliba by the 2nd century AD, i.e. after the conclusion of the Dacian Wars, the draco symbol was assimilated in the Greco-Roman world with the Dacian ethnos. According to Jon N. C. Coulston the Romans associated this standard with 1st and 2nd century Danubian barbarians. The Roman historian Arrian wrote that the Romans took the draco from the Scythians, most probably a term for the contemporary Sarmatians.

Cristina Rus (born June 21, 1981), is a Romanian dance music singer, dancer and model from Cluj Napoca, mostly known for her past collaboration with Andreea Banica in the group Blondy. She is also known for her current solo career. She has twice reached in the top 5 Romanian MTV music charts with her singles Viata mea ('My Life') and I Don't See Ya.

Rus began her career as a model at the age of 14. She worked with famous Romanian fashion designers, such as Catalin Botezatu and Zina Dumitrescu. Passionate about music, she started studying canto courses at a local music school in Cluj-Napoca. She was later discovered by Sandy Deac from the group Desperado, setting her music career in motion.

In 2001, she met Andreea Banica, a singer that she had wanted to work with. She left Desperado to create the band Blondy with Banica. They became famous in Romania with songs like Ai gresit, Fiesta, Numele tau and Cu tine vreau sa traiesc.

In 2004, Blondy broke up due to a big quarrel^{[citation needed]} between Rus and Banica. They both decided to embark on solo careers. Rus has remained a well-known singer in Romania.
