Vanjarls get no randoms, although the Vanadrotts do. But at 380 gold apiece, you won't be making many of those, so the odds against a random coming up blood are pretty high. You pretty much need to decide at pretender-creation time whether or not your Vanheim will be a blood nation. I often use a 4 water, 4 blood Dragon for the pupose. Decent blessings, not bad at early province taking, and able to summon Ice Devils and forge blood-empowerement items. After an affliction or 3, your dragon retires to a lab, and jump-starts the blood process...
