Dark Gauntlet

Dark Gauntlet is the cave associated with Duach's temple. If your alignment is Malevolent, Evil, or Demonic, praying at the altar will give you glowie red/black hair and 90% poison resistance (meaning you only take 1 out of every 10 poison counters you would have otherwise) for 6 game hours or 360 combat rounds. Any other aligmnent will get you cursed, giving you gray skin with a red outline, cursing you with Defenselessness, and making all shield magics (including Invulnerability) not work for you for 6 game hours or 360 combat rounds. Game hours are the time you are logged in to Realm, not real time.

To get to Dark Gauntlet, go 7 squares left from the East Leinster teleporter and pray at the altar in Duach's Grotto, then go 2 right and 1 down from the screen you're teleported to. Once inside you will probably be ambushed on the first screen. (The usual ambushes are Undead Necromancers, Daemon Ratlings, mixed Fenris groups, or, if you're really unlucky, 2 Banshees and 2 Furies. Plus the bonus no extra cost free Hell Soul, of course.) Fight the ambush, then go 1 right and 1 down, where you'll fight 2 Daemon Ratlings. Go 1 right after that and type Vanity in the room tab to open the door. Go 1 down, 1 right, then 4 more down. Go 2 left and fight 3 more Daemon Ratlings. Go 1 left, 2 down, 1 left, 1 down, 3 left, 1 up, 1 left, and 1 more up for the biggest fight of this route, 2 Flame Daemons and 2 Daemon Ratlings. Finish them off, go 1 up, 2 right, 2 up, and 1 right for the last fight, 2 more Daemon Ratlings. After that, go 1 down, and pray at the altar.

There are other ways through, but this is the quickest. No treasure drops in DG, and your alignment will not change from fights within the cave.
