I'm hoping I'm not being a bother by asking so many questions here... I've received a lot of very helpful replies, and I appreciate all the responses I've been getting. But I'm afraid I have another question...
So, I was working on an adventure for the Jonstown Compendium, which I was going to set in Ten Spear. Only it turned out Ten Spear had already received a lot more development than I thought (albeit mostly in the noncanonical Tales from the Reaching Moon), so I decided to set my scenario in Marshedge instead.
One problem... I found two maps that show the location of the Marshedge Clan, and they completely contradict each other.
The map in Wyrm's Footnotes #15 (page 17) shows the Marshedge clan along the Sword River, northeast of the Lonendi and west of the Goodsword. But this map of Central Sartar on the Well of Daliath shows the Marshedge clan west of the Lonendi (and shows the Lonendi and Goodsword directly abutting). Either location would work fine for my adventure; I just wanted to know which if either should be considered canonical so I know which one to go with. On the one hand, Wyrm's Footnotes #15 was a physical publication, while the Well of Daliath is just a webpage, so maybe Wyrm's Footnotes takes precedence. On the other hand, Wyrm's Footnotes #15 was a physical publication from ten years ago, while the map on the Well of Daliath was just from last year, so maybe the Well of Daliath map takes precedence.
Does anyone have any thoughts, or is there a definitive answer?
