The fomor was apparently supplying weapons and other material to the rcv for their war effort so they likely had great influence for their strategies.

I think the stone table can help kill immortals, but in a way allow them to be reborn.

The ritual was aimed at killing him, all he just did was redirect it at his enemy. Destroying their power of his inhuman enemy. Classic white council doctrine. The thing is those rcv were sustaining mortals, so when removed, they aged die.

I have to wonder if there is a sword hidden away for the warden of the well. The position might predate the swords, but it would be a powerful artifact to supplement him.
Just like how Harry can use McCoy staff, a warden could use warden tools. Also, he could borrow Mccoys warden sword, it is sure to be better than those off the shelf sword most warden have.

It is believed the gift to the dragon was tainted, similar to the athame. If added to the treasure hoard, could it alter the curse on it?

It is said immortals feed upon each other it think, so they would count as living weapons.

A dragon hoard is cursed, but what if the treasure is taken after it has passed through multiple hands. The treasure is set to go after thieves, but after a couple dozen transactions, are they still thieves.
I totally see someone using cursed treasure to eliminate others, then reclaim it safely.

There is a common theme of you can't protect yourself from your own energy. I wonder if the curse is best suited to mess with dragons, they would see each other as the greatest competition.

While the curse is sure to be awesome, I still think there would be ways to by pass it. Dresden is always learning secrets that would get him killed so why not one more. We know there are very few true dragons left, 2 I think, so there treasure would be very useful. Not for the wealth, but the artifacts, knowledge and magic they would contain. They might be a treasure hoard, but you can bet, there is enough to make it an armory in the right conditions.

The lands of faerie are the closest region of the never never, closest to the material world. Many of the most known, used or safest ways are through the lands of faerie. I am betting that due to Maggie knowledge of the never never, and contacts amongst, she knew every way in the lands of faerie. That Alone would be valuable.
