Wrong (Ultima V)

In Ultima V, the Underworld below Wrong leads to the Shard of Hatred and is connected to Covetous as well. Traversing both dungeons is not essential to winning the game; one will suffice, except to gain Experience and treasure. To get straight to the Underworld:

Level 1: Go into the room and down the ladder.

Level 2: Head all the way south, turn, dispel the electric field with An Grav or the sceptre, search the next space to reveal a pit trap, and go down it (or the ladder beyond).

Level 3: Ignore the rooms and just continue down the ladder.

Level 4: Head south and down the ladder.

Level 5: Look for a secret door to the north of the ladder; on the other side there is a healing fountain to the northwest and a poison one to the northeast. Then continue south, take either fork, dispel another field, and take the ladder at the end of either corridor.

Level 6: Go down the first ladder encountered (before passing the fire fields).

Level 7: There are secret doors on all sides, but they can be bypassed.

Level 8: Find the secret door in the north wall, use the fountain to heal, dispel another energy field, and beware, because every step from this point onward will have a bomb trap for which adventurers must search. The room on the corner has a number of hostile magic users, so the Crown or an An Tym spell may be worthwhile. Exit to the south as quickly as possible (or kill them and attack the fireplace to reveal some treasure) and proceed through one last field to reach the ladder to the Underworld.
