I was going through the web site, making sure I had ordered all the Throne of thorns books, and I was able to identify the following based upon their description on the web site
1. Thistle Hold - Wrath of the Warden
2.
3. Yndaros - The Darkest Start
4. Symbar - Mother of Darkness
5. Alberetor - The Haunted Waste
6. Davokar Awakens
Which one is #2? The only other campaign book on the web site is KARVOSTI – THE WITCH HAMMER and it doesn't mention the Throne of Thorns.
