The "aclla" had been blessed by the Emperor and became the guardian of the local huacas. This signaled the entrance of the empire into local tradition and religion. Acllas were an extremely important tool of statecraft for Cuzco. They figured heavily in the system of reciprocity that kept the empire running without a formal monetary economy. Redistributing women was an extremely successful way of gaining the loyalty of those who had just been conquered by the Inca because it conferred status to the families of selected women and helped to build trust between officials and locals. Their service was also essential for establishing the Inca culture across the empire. The labor that they provided in the form of textiles was used in gift giving to help form alliances and they themselves were also used as a kind of gift that helped to confer status on the recipient. Those who received an accla as a wife also received all of the skills she could provide which allowed that person significant power. Acllas given in service for religious purposes conferred importance in a similar way because of their skills in creating the necessary means for rituals, namely the brewing of chicha that was integral to religious ceremonies. Their presence is noted at the ritual site of Huanaco Pampa, where the structures that have been excavated suggest a large presence of aclla who had access to the extensive storehouses of corn and grain to make chicha. It was important that they were present at the site because chicha could not be stored for long periods of time; it had to be made more or less on the spot. While less common, there is some evidence that acllas were used in human sacrifice. This was tied to their role as gifts and the system of reciprocity throughout the entire empire due to their economic significance. In a ritual context, they were an extremely valuable sacrifice because they represented the capacity for so much potential wealth through the use of their skills in weaving, the brewing of chicha, and hospitality. They also represented a connection between Cuzco and the peripheral regions that they had conquered. This tying of the centre to the periphery was one of the most important aspects of the sacrifice of "acllas". The story of Tanta Carhua is one such account of the process of binding the centre and the periphery together. Colonial documents contain record of Tanta Carhua, who was sacrificed as a "capacocha" in her home ayllu of Urcon. After visiting Cuzco and being honoured by the emperor, Tanta Carhua was credited with saying “You can finish with me now because I could not be more honoured than by the feasts which they celebrated for me in Cuzco."
