Quellcrist Falconer

From "Altered Carbon" (2018), Quellcrist Falconer (née Nadia Makita) is a leader of the organization known as Envoys. She is also responsible for igniting the rebellion flame within the UN Protectorate, as well as for designing and ultimately engineering the very first cortical stack. Falconer managed, through her followers, to give birth to a whole new eponymous religion called Quellism, which many throughout the human empire related to and embraced. Quellcrist and her Envoys, along with the rebellion itself, were ultimately defeated at the battle of Stronghold, the former being sleeve-killed. Unbeknownst to the unified government, however, her stack had been backed-up before her demise, preventing her from experiencing real death.
