Safekeeping the Koh-i-Noor
Bolden survived the fall and was brought to a local hospital, where he was treated. After the incident, Bolden failed to report to his superiors, which led to the Order sending Rufus Grosvenor, a high ranking member to find out what happened to him. A year later in a Chinese opium den in 1928, Bolden encountered Grosvenor, who attempted to blackmail him, threatening to reveal to the Order that he is alive if he didn't gave him the Koh-i-Noor, but Bolden refused and left.
Knowing that Grosvenor would track down the artifact eventually, Bolden travelled to Switzerland and retrieved it from the bank it was secreted in. For the next 9 years, Bolden kept the artifact with it throughout his journey to hid it from Grosvenor.
Sometime in 1937, Bolden returned home to find his family murdered and the Piece of Eden stolen by Grosvenor. Vowing revenge, Bolden tracked the Templar for the next few months, eventually to Spain, where he finds Norbert Clarke, Ignacio Cardona holding the Koh-i-Noor and a group of Spanish Assassins in the Assassin hideout. As Cardona pass out due to the usage of the Piece of Eden, Bolden attacked Nobert Clarke and the Assassins which caused him to suffer several bullet wounds. Unable to get close to Gorsvernor, Bolden took the unconscious Assassin instead and escaped to a unknown location.
At the hideout, Cardona regained conscious as Bolden was patching up his wounds. Bolden revealed himself as a Templar and the Black Cross which led to the Assassin attacking him. Bolden easily subdued him and explained to him of his 'death' in Shanghai, how he encountered Grosvernor and tracked him to Spain. He revealed that the Assassin Norbert Clarke was actually Grosvernor, who had killed him earlier and posed as him. He also tells Cardona that Grosvernor was planning to use him as a conduit for the Koh-i-Noor and unleash its powers. Bolden asked Cardona to help him track down Grosvernor, in exchange for helping him to warn his cell, which he accepted.
Bolden and Cardona rode along with several Spanish revolutionaries and a while later, they come across Grosvernor, with the Assassins behind him.
In 2013, Juhani Otso Berg watched the memories of Darius Gift in order to learn more about his encounter with the Black Cross. Indeed after Berg's mission in India, the Templars discovered that Bolden was the last recorded individual in contact with the Koh-i-Noor, a Piece of Eden.
After witnessing Bolden fall from a temple roof, having been shot multiple times by Gift in 1927, Berg told Violet da Costa that despite the evidence, he wasn't sure that the Black Cross truly died that day. Bolden's family disappearing from the records after his departure for WWI, Berg put the search for the artifact on stand-by, hoping that the Order would find one of Bolden's descendants to further explore the Black Cross' memories.
In 2017, Berg relieved Bolden's memories during his time in Spain during the Spanish Civil War in order to locate the Koh-i-Noor.
Albert Bolden was a capable freerunner and climber, able to scale buildings in London and China. He was also a skilled tactician, allowing Thaddeus Gift to get to a phone to reveal his collaborators, and accounting for Yuri Dolinsky's superior sword-fighting skills by cutting the tracks of the train prior to their duel on board, causing Dolinsky to fall and lose his advantage. Bolden was a trained soldier and was a skilled marksman knowledgeable with many firearms.
Albert was also highly skilled in unarmed combat besting many opponents in the crime syndicate the Green Gang, such as the large Fiery Crow, and holding his own against the skilled Flowery Flag. Even while injured, he held his own and outmatched a rage-filled Ignacio Cardona four times. He could take down multiple opponents in close-quarters combat, such as when fighting multiple soldiers at once in the Great Wall or when he faced off against an entire assassin cell, although he was forced to retreat. He was also exceptionally skilled in stealth, constantly sneaking up on those he had to interrogate or execute. He was fluent in Chinese.
In terms of equipment, Albert carried a bladed pin as his primary weapon; he had two poisons for it, one fast and another that took hours or so to set in. He also carried a sword on occasion and possessed what appeared to be a kind of chain dart, along with smoke bombs, grenades, a sub-machine gun and a gas mask.
- He indicated that he has eliminated entire assassin cells more than once.
