- "Don't slay the messenger, good Lord. Have my pouch instead."
- ―A Borgia messenger, upon being caught.[src]
Borgia messengers, also known as Borgia couriers, were messengers for the House of Borgia. They always carried a significant amount of florins with them, likely delivering payment to or from allies of the Borgia.
Fast traveling through the tunnels from Tiber Island to the Thieves Guild would cause a messenger to appear, usually within a minute by simply looking out to the road, every time coming from the left side of the road.
He sometimes also appeared behind Ezio, climbing the guild building. Repeating this process enabled the "farming" of messengers to obtain florins or shop quest items, such as the semi-rare item Aconite.
Back at Tiber Island, a messenger would also appear to the right of the guild entrance. After around a minute, a messenger would run past.
