Hi,
I'm not sure if it is intentional or was missed but, an entire degree of relationship has been left out from many main characters information pages.
For example, Rudeus is correctly identified as Eris's husband and Paternal second cousin.
However, they are more closely related than the above. They are also Maternal first cousins once removed!
Rudeus's father is Paul Greyrat . Pauls' mother and father were both Greyrats and first cousins once removed, thus, how Rudeus and Eris are paternal second cousins.
However, Paul's mother, Valentina Notos Greyrat, is the sister of Sauros Boreas Greyrat.
Therefore, Valentina's son Paul, and Sauros's son Philip are first cousins. That makes Paul's son Rudeus and Philips daughter Eris, Maternal first cousins once removed!
That means, for another example, while Rudeus's son Ars is correctly identified as Aisha Greyrats Husband, Half-Nephew, Paternal second cousins once-removed, the information that they are also Maternal first cousins-twice removed is missing.
What a tangled family tree indeed!
