You step away from the bodies of your slain enemies and collapse against the wall of the vault, gasping for breath. As you slowly recover, you notice that one of the reptilians has a leather pouch slung around its neck. You kneel down and tear open the pouch to discover that it contains a small Iron Disc. A cursory search of his dead companion reveals a Dagger, a Sword, and a small stone phial containing a Black Potion (properties unknown).
The size and shape of the disc suddenly trigger an image in your memory. You take the disc and insert it between the gemstone squares which operate the portal lock. There is an audible click! and the disc reappears at the slot. (If you wish to keep this Iron Disc, record it on your Action Chart as a Special Item.) Seconds later, the heavy portal begins to rise. You wait until it has risen a few feet and you are sure that no enemy awaits you on the other side; then you duck under the iron plate and hurry into the tunnel beyond. As you run, you hear the portal slamming shut behind you with a dull reverberating boom.
