The Cygnet was a financier of the Templars.
In 1491, he was at a town on the road from Zaragoza to Granada where unbeknownst to him, he was being targeted by the former Assassin Helene Dufranc. To his fortune, this rogue ran into the Assassins Ezio Auditore da Firenze and Raphael Sánchez and revealed her objective in the midst of her banter. Having heard of the Cygnet, Raphael bid Ezio to follow Helene so as to learn of the man's face for future reference.
More importantly, neither Assassin desired harm to come to him, as it served no purpose and could alert the Templars to their presence in the area. Accordingly, Ezio raced Helene to the Cygnet's location, intercepting her just before she could spring her attack, much to her annoyance. Spared from assault, the Cygnet remained ignorant of nearby Assassin activities, and Ezio and Raphael safely continued on their way to Granada where they would foil the Templar plot to prolong the war against the Moors.
- Cygnet is a word denoting immature swans, derived from Latin cygnus, meaning 'swan', with the diminutive suffix -et.
