The Realm of Angbar: Elfhelm's Bane is a 1984 Apple II text adventure computer game, created by Mark Peterson and published by Green Valley Publishing, a division of Share Data, Inc. It is a fantasy game, with elements inspired from Lord of the Rings, Dungeons & Dragons, and Scepter of Goth. It is much more than an interactive fiction game; it is a role playing game with level advancement, battles, spells, items, and much more.
You can check the Disk Images site for updated links to the game, which is now abandonware.
