Hunting the Koh-I-Noor
Before World War I, Grosvenor was a member of the Templar faction which followed the Master Spy. Twelve years after the death of the Sage, Grosvenor found the trace of the missing Albert Bolden in a chinese Opium den. He tried to blackmail the former Black Cross, threatening to reveal to the Order that Bolden was alive if he didn't gave him the Koh-i-Noor, but Bolden refused and disappeared while Grosvenor was turning his back on him.
As a result, Bolden resolved to take the Piece of Eden from the Swiss bank it was secreted in and constantly moved around the world with the diamond on him. During nine years, Bolden escaped the Templar goons that Grosvenor sent after him until he fell into a trap. Having discovered the location of Bolden's family and that his prey was regularly visiting the place to check on his loved ones from afar, Grovenor raided the house and butchered the Boldens as well as their dog to make a macabre scene and to lure the Black Cross inside. As a distraught Bolden discovered the gruesome fate of his family, a hidden Grosvenor used his distraction to knock him out and to take the artefact before fleeing.
Needing someone with a high count of Isu DNA to unlock the powers of the diamond, Grosvenor went to Spain where he planned to manipulate the Assassin Ignacio Cardona to do so. To approach Cardona, the Templar stole the identity of Nobby Clarke, after he manipulated the veteran British Assassin sent to help his Spanish brethens into taking his own life.
When he arrived at the Barcelona hideout, Grosvenor sneaked inside but Glaucia wounded him. He ran to the rooftops with Glaucia in pursuit. She eventually caught up with the two of them coming crashing down through a broken roof. Playing the act, the Templar presented himself as Nobby Clarke, their Assassin backup sent from London.
They safely returned to their hideout, where the Spanish Assassins interrogated Rufus as to why he was the only backup that was sent considering how desperate they are for help. "Nobby" revealed that he was the Assassin who famously eliminated an entire Templar branch in Tallinn the year before, which instantly won him the approval of the Spaniards. Ignacio requested that the team train with their British brother on the rooftop to see his skills first hand while he ventured out to try and find new weaponry, as their current ones were in a bad state of repair. During their training, Rufus and the Spanish Assassins started discussing the split between the anarchists and communists within the community.
Soon after, Ignacio ran past the group, insisting they all follow. They reached a fevered gun battle between anarchists and communists, with the team undecided on which faction to side with. Using this opportunity, Rufus offered Ignacio an alternative, saying that the latter could make the team stop their in-fighting. The Templar then pulled the Koh-i-Noor out of his pocket and offered it to Ignacio, who stated that he felt it calling to him and touched the diamond.
Immediately his eyes started glowing with a blue energy, and serpent-like creatures of energy emerged from the Koh-i-Noor, encircling and wrapping themselves around everyone. With blood pouring from his eyes and nose, Ignacio dropped the diamond and passed out. From a nearby rooftop, the former Black Cross Albert Bolden, who wanted revenge on Grosvenor for the murder of his family, observed everything that transpired.
