So, I present: the Angband sweater.
Edit: In answer to your questions, the sweater is an adaptation of Rogue, in a modification of the 39'' size to allow for my row gauge being too small. It took me 15 balls of Debbie Bliss Merino Aran (just about exactly; I had maybe two yards of yarn left over).
The spider is from Barbara Walker's "Charted Knitting Designs". The tree is something I designed, based on the one on Arwen's banner at the end of Return of the King. I'm not completely happy with the way it turned out; I'd want to rework the tree before I transcribed the pattern.
Third edit: The completed, revised chart has been made and is here.
