The First Painting was an altered representation of a fragmented genetic memory.
Aguilar's Journal
Da Vinci's paintings cannot stay in the Inquisition's hands! Captain Diego has given away each piece to his underlings, and they are now scattered across Spain. We must recover all the pieces so the set can finally be sold to finance our fight against the Templars.
The first piece was given to Diego's personal confessor, the Abbot of Santa Claudia de Las Huelgas, and is being stored in his abbey. We will sneak and lockpick our way through and recover the painting.
Outcome
The Spanish Assassins successfully retrieved the first painting from da Vinci's The Celestial Mysteries set.
