King Pellam’s feast is coming up and this invisible knight will be there, too. Note about blood: blood is a paradox in that it is regenerative (healing properties) as much as it’s loss brings death. Blood ties families together, blood heals, and Christ’s blood is eternal (sangreal). Anyway, it takes 15 days to get the the feast but will not give up his sword to enter the castle.
