The Hegemon's Heart are the crystallized ventricles of the first Than-Thre-Kull hive queen. They attach great importance to the artifact. During the long night, the Hegemon's Heart was stolen by Doge Miskich to be put on display on his drift, Pierpont Drift. The Than hold the heart in such high esteem that in order to get the heart back, they were ready to begin a war against Doge Miskich. The aforementioned war was only averted by the fact that Doge Miskich asked the Andromeda Ascendant for assistance.
