Shadowkeeper lets you edit characters and save games. You can open a previously saved game and edit everything from a character's name, stats, THACO,armour class and the amount of gold carried by the party to the spells thay can cast, how they look (not just the portrait but also the in-game figure), global variables, resistances, items and names. By typing the desired number, dragging down a slider bar or pressing an edit button, you can do almost anything to your party members.

The last arrow of Legolas kindled in the air as it flew,
and plunged burning into the heart of a great wolf-chieftain.
All the others fled. -J.R.R. Tolkien, The Lord of the Rings
