For those who are lazy (or frustrated) I decided to add a few spoilers. If you don't want it spoiled, don't read this thread!

1. The Master of the Hunt tracks are the following animals: Bear, Boar, Cockatrice, Deer, Lion, Vulture, Cold One, Salamander. You have to kill 15 of each. All but the Cockatrice and Salamander can be found in T1 Elf lands, but the earliest the Cockatrice and Salamander appear in the normal world is in the Shadowlands. Lions can be difficult to find for order, as most of the lions in T1 are on the dark elf side, and con friendly to Order. There are a few in chrace that are orange, and thus attackable, but you can also kill mountain lions in Mount Bloodhorn. The best place for vultures, that I've found, is in Norsca (where they tend to be generally hanging out all over the place). All of the beasts may or may not exist within the Vale of Vines... I haven't yet explored the entire zone.
2. The quest "To Deny a God" is obtainable in Altdorf/Inevitable City. It's pretty easy... there are Sacred Bears of Kurnous scattered all over the T1 elf lands, and they're all around lvl 5.
That's really about as far as I've gotten... the Master of the Hunt took most of the day because I was on a T1 alt and thus didn't have the freedom to travel around killing stuff to find the tracks. That and I spent about 3 hours trying to find Raccoons for the Salamander tracks.
