I find a couple of mistakes here. First of all, when the Dracon birthed the Eldest, he gave it to the Ruthven lineage (to Damek Ruthven to be precise) in Sarmizegetuza Dark Ages Novel: Tzimisce. Then Shaagra was not a childe of Yorak, her sire is Triglav, although she never met him Clanbook Tzimisce Revised, pg. 17.
