Their delusions are quite malleable and seem to be more in tune to how they view their enemies rather than a specific chapter for a specific species. They may view a ordo hereticus inquisitor as a black templar or a minotaur depending on how they collectivly perceive their emotional aura. So a eldar may be a dastardly red corsair or a grim lamenter depending if they are talking to a corsair raid fleet or a friendly iyanden diplomat. Their tolerance towards xenos is a hot topic with the inquisition and the ordo astartes but they recognise their schizophrenia and since they haven't really fucked anything up by doing those alliances their quirks are tolerated.
And yeah, they are of Blood Angels stock and particularly interested in imperial history and ancient artifacts.
