Looks like there have been a few changes since I was last in the game regarding Page 5 of this book (and the addition of Elite training). Page 5 now requires you to kill 6 Wild Sheep and 1 member of the Goblin family. It's still focused on the La Theine Plateau area.
Although I haven partaken of the Elite training "exercises", I'm guessing they're meant for higher level individuals (at this point I don't have enough tabs to go investigating them), but I may be wrong.
