Helaquin

Helaquin is the wife of one time Bretonian Nobleman Harlaquin, and was for most her life a member of the Ravenholdt Order alongside her husband and best friend Harlaquin. She would join her husband when Ezio arrived and asked for people to follow him to found the Order of the Violet Dragon.

The Performance
It was while on a mission to assasinate a target in the Empire that Harlaquin and his wife Helaquin would gain their fame, as well as cement their loyalty to Ezio.

"Cahin laughs his way through the door. Caha tips over a candelabrum before tumbling out behind him. I remain convinced that they are totally mad... yet fun!"

-Ezio while watching The Quins during the performance

Cahin and Caha performed together, so as to lure an assigned target - a foreigner with some claim to royal blood - into the open. As Helaquin distracted their audience by juggling her daggers, Harlaquin slipped away and stabbed the man through his chair. In the chaos that followed, Harlaquin, Helaquin, and their ally, Ezio, finished off the rest of the guests.

Harlaquin
Her husband and best friend is Harlaquin and since the two were small children they always talked about being together forever. They are rarely ever apart and they do not do solo missions.
