Ignatius's Links
Ignatius and Sirius can be quite the pair. Both are irritable at times - something Ignatius takes from Sirius - however where his father is cold calculation, Ignatius is fiery rashness. He does get along well with his father, and find unconditional support.
Sirius is not known to be soft towards others in his life, but Ignatius is a part of him and as such there is an easy bond between the two. He loves his son, and does all he can to assure that his eldest grows up knowing his parents would never leave him.
Ignatius looks up to his father, Nikolaos. His admiration is something he developed in his childhood and retained into his adulthood. Niko is a source of council should Ignatius need it, and clarity when irritability clouds his judgment.
