1124: The big book of seals. Contains detailed descriptions and artful drawings of all seal, sea lion and walrus species in the world (of the setting). It contains enough information for those who need to be familiar with an animal in order to for instance identify, handle, summon or shapeshift into it to count as being familiar with all of them while the book is in their possession or after spending 2 full days studying the book. Studying the book as part of a long rest makes a character familiar with a single species of their choice. A person has to be literate in order to use the book, or hit a 5 on a Decipher Script check (int, as an exception not trained only, try again: no).
