I see it in game in the World Events tab, in the Achievements window. Just hit on Pilgrim (from the right pannel not the drop down list on the left) and you will see the achievement awards both the title and the pet. I shall finish it tonight as I am 2/3 done allready. I like how I get Grand Master Cook from a world event.
Such a pain in the ass to get all those races turkyed down. They dont need to be on a mount, or in combat. I find it hard to get it on a Dwarf Rogue. I found one yesterday, but with my luck, the server went down before I finished my cast.
