The Palantir of Westernesse

The Palantir of Westernesse was a quest artifact from versions of NetHack prior to 3.3.0. This was the version which introduced a choice of starting races, so the old Elf class was removed, along with its quest and quest artifact.

The Palantir of Westernesse was a crystal ball. When carried, it granted regeneration, ESP, and half magic-damage. When invoked, it tamed nearby creatures.
