This diagram shows a detail from the House Imago family tree.
One of the reasons that I explored this family tree in such detail is because I wanted to explore how a House might lose its first lineage. Such a loss occurred in House Imago 95 years before Carnelian is born, when a father and son (shown in orange) were involved in the succession crisis of the God Emperor Qusata. Their blood taints were close enough to his that it was required that they be executed at his Apotheosis. Many other Houses lost their first lineages at this time. Jaspar is a descendant of an offshoot of that first lineage, that before the crisis had been destined to be a second lineage.
House Imago gave a bride to the House of the Masks, Urkare, who was Osidian’s great great great great great grandmother.
Note also the link between House Imago and House Suth. Jaspar’s great aunt became Suth Sardian’s grandmother.
