Nikolaos of Sparta, also known as the Wolf of Sparta, was a Spartan general who lived during the 5th century BCE. With Myrrine, the daughter of King Leonidas, he was the father of Alexios and step-father of Kassandra. He was also the adoptive father of Stentor.
Because his step-daughter was descended from Leonidas, Nikolaos had high hopes for her to live up to their grandfather's fame and valor. However, a catastrophe befell the family one fateful day when an Oracle prophesied the destruction of Sparta at the hands of Myrrine's children. Following the apparent death of Alexios as a result of Kassandra's actions, she was sentenced to death. Nikolaos reluctantly stood by this sentence and personally attempted to carry it out, only for Kassandra to survive, and, in exile, grew up to become a legendary mercenary.
By 431 BCE, Nikolaos was posted in Megaris to conquer the city of Megara with Stentor, an officer whom he had adopted sometime between 448 and 431 BCE. The army was later assisted by a mysterious Spartan misthios. When the Spartans succeeded in conquering Megara, Nikolaos requested to meet the misthios in person, waiting on the edge of a cliff. The misthios revealed herself as Kassandra, who had survived the fall years ago. Though desiring revenge, Kassandra ultimately sparred his life. Nikolaos later revealed to her that he was not her biological father and that her mother was still alive, before abandoning his post.
2 years later, Nikolaos returned to his post, secretly assisting his adopted son Stentor in his efforts to conquer Boeotia. To this end, Nikolaos went after Aristaios, one of the Boeothian champion who was stationed in Gla at Lake Kopais. While executing Aristaios outside the fort, he was found by Kassandra, who had been dispatched by King Archidamos of Sparta to assist Stentor.
- Nikolaos (Νικολαος) means 'victory of the people', from which the English form, Nicholas, is derived.
- While Assassin's Creed: Odyssey allows the protagonist to choose between sparing Nikolaos or killing him, the official novelization confirms that Kassandra spared him during their reunion in Megaris, and later helped him reunite with Stentor after his 'official death.'
