This 209 page book is full of creatures to populate your Talislanta world.
From the first page of the book:
"Welcome to the Talislanta Menagerie: a compilation of flora and fauna found throughout the continent of Talislanta and other dimensions and planes of existence. Talislanta was first fully documented in the year 600 N.A. by the wizard Tamerlin in his renowned The Chronicles of Talislanta. Since this estimable tome has recently been updated and re-released to the world of academia, now is an ideal time to bring Talislantan scholars up to date on the natural (and not-so-natural) world. Apart from random notes and scrolls of the naturalist Thystram, a number of sources have been used to compile the Talislanta Menagerie.
