I am usually very much an advocate for bringing the WizKids material forward into the Catalyst-side of things, but Alaric's heritage is a tricky matter. For one, Masters of War completely reverses the genefather/genemother dynamic that any clanner knows at his core. Ignoring the VSD aspect for now, Katherine would never have been his genemother as she isn't a bloodnamed warrior. Claiming eligibility for the Ward bloodname means Vlad Ward is Alaric's genemother (at least as far as the paperwork is concerned). This all should have been caught by fact-checkers (or the author considering how many clan novels he's written). For whatever reason it went through making this all a mess.
Beyond that nit-picking, there's the fact that in a post Wars of Reaving Clan Wolf, you have scientists willing falsify data and engage in un-clan-like genetic modifications with warrior genetics is shocking to me. Katherine is a special case, but after Vlad's death, Ivan Kerensky and subsequent Khans side-lined her power and access. My personal take is Alaric's genemother is Vlad, genefather is Katherine and the stuff about Victor is just more psychological manipulation by Katherine. DNA testing should be a simple way to prove the truth.
