I was questing in Felwood tonight when I wrapped up the Grizzly quest and saw and owl that I almost attacked, just for the heck of it. I saw a named creature in my mini-map from my Track Beasts ability. I ran over and saw it was a huge white owl with a yellow combat status. It would have been my first owl kill in Felwood with Hunter. Then I saw purple text appear in my tooltip telling me that he was rare.
Olm the Wise is one of 4 owls/owl-types in the game that has this skin color, according to Petopia.com. I did have to set my rep status to be At War with Cenarian Circle to tame him, but that was no biggie. He went right into my ice block Freezing Trap and I tamed him with only about 10 seconds of getting hit. (location: 55.7, 21.5)
Here are my screenshots. Notice his new name. 42 points for the first person with the reference.
Oh, yeah. Ding 54. 5d 10h 26m /played time.
