Well, some bloodnames are easier to resolve than others . . .
Star Captain Victor West is killed by the Wolf Empire in a trial- his Conjurer lost its head in the latest Trial of Possession.
Because they know a West Bloodname is suddenly vacant, any with the West Bloodname in the Spirit Cats in the Protectorate get to nominate one unblooded for the Trial and whoever is the Bloodhouse Leader fills in the rest of the field- supposing they have 32 warriors in the ranks able to compete. If not? IMO the warriors nominated by current Bloodnamed would get a first round bye. No West Bloodnamed among the Spirit Cats? Rikkard as the leader would be Oathmaster and standing in for the Bloodhouse Leader, would fill the field . . . unless there was not enough to really make a go- after all, do you want to give a bloodname to someone out of a field of 3 candidates? If that were the case, it may go dormant waiting for sibkos to come of age and experience combat.
Spirit Cat bloodhouses are going to have some problems unless they plan to perform some Trials of Propagation in about 15 years, or declare claims over names vacated by the Combine's extermination. The reason I say this is they have already been forced into ever narrowing options . . . what they had claim to was the Bloodnames of those who went with Delta Galaxy into the Republic- and some of those names could have been challenged for by regular Nova Cats, we do not know- then we know not all the Spirit Cat forces made it to the Protectorate. Kev Rosse died in the Republic and so did other Spirit Cat units, either from fighting against the RAF, other splinter groups or Houses. So the reason Rikkard may not have a bloodname is that all the Spirit Cat holders either died in the chaos of the Fortress being established, or was behind the Fortress wall when it went up . . . and they would have no way of reliably getting information about the name being vacated. IMO its a real question of did Rikkard's Spirit Cats even get any genetic legacies from their enclaves in the Republic.
Additionally, the first Spirit Cat sibkos should be about 10 y/o and if they had the legacies available setting up the sibko system would be easy with their powerful allies. I wonder if the Foxes also took possession of the Nova Cat genetic repositories/legacies when the Dracs went stomping. They seemed to have a agreement standing by for the Nova Cat property.
