The whole concept of bloodlines and their magical powers is well-known. Noble houses gifted with a divine bloodline are proud of it and usually make a big thing of it, very often being able to mention every single ancestor back to the original hero who was present at the battle of Deismaar. There are also spells and divine powers of the blooded scions that allow for detection of divine blood, its strength and derivation as well sometimes. The details are not common knowledge however. It's mostly a subject that one leaves to dedicated scholars who research all descendants of a particular line and their powers. Church of Ruornil is one of those who deal in these kinds of studies.<br/><br/>You all know what your bloodline is by now. How you came upon that knoweldge is up to you.
