Beastiary to view information on enemies

I dont know if this is a planned feature or what but i think a beastiary would be amazing. All the enemy types are so cool looking and having a way to veiw them up a bit better would be awesome. It could just be a menu option but i my mind the ideal thing would be a build you unlock and upgrade. Like a traveling scholar or historian, going from book stand to full blown class room. Could have things like the more you kill the more you unlock lore pasages about them maybe even unique stuff like art works for your house or something.
