So, you thought that Shivering Isles was going to be the last plug-in/expansion? Well, you were wrong. Bethseda is making a new plug-in to add to the list of them. Dragonfire Castle. This is a plug-in meant for heroes and knights. (finally it came...) It is a castle that a family needs to sell for 100,000 gold. (Finally something to waste your septims on...) Here are the features that I know of for now:
-A Secret Vault
-Wine Cellar and Vinter. Lots of Fighter-Aiding wines and a vinter to make them.
-Combat training and sparring room.
-An NPC for weapon skill training.
-An NPC that follows you around and helps you in combat.
-Dwemer Forge. Boosts Armourer skill by 15 for short time.
-Trophy Hall and Taxidermist. Another NPC will make stuffed forms of creatures when you bring the proper ingredient, the critter will then appear on a podium in the Hall for your viewing pleasure.

I am unsure of how much points this will cost but I guarantee this will be better than some of the other plug-ins (I find the Orrery a waste of points).
