The Family Index

The registrar sighs deeply before reaching behind himself to grab a faded tome with a tattered red cover. He blows the dust off the cover and reveals the gilded text- 'A Complete Guide To All Lineages'. He grumbles in annoyance- 'They are sorted by registration date. I'm not rewriting the whole book everytime someone decides to bond two creatures'- before he quickly hands it to you, and returns back to reading his magazine. Interestingly enough, it seems to have the cover title 'Cooking Without a Fullbody Hairnet'.
