Landri

Landri is a shepherd who could be found in the environs of Castle Britannia during Ultima IV.

Description
The grim man stood near the secret entrance to the Dungeon Hythloth, and would warn the Stranger of the perils that lay ahead, pleading with them to turn back. He would tell the hero that once they set foot in the passage ahead of them, they would never be able to return through that route.

Trivia

 * In the Nintendo port of Ultima IV, Landri appears to have been replaced with an unnamed female mage with similar dialogue.
