Naljier Skal

Naljier Skal is an unhinged bard who can be found amongst the inmates at Spellhold during the course of Baldur's Gate II: Shadowns of Amn.

History
Naljier Skal was apparently once a bard of some repute and a skilled mage who was known to conduct experiments into planar travel and divination. From what little is known, he attempted to work some magic to divine what lays "beyond the gods", and, according to Jon Irenicus, something apparently didn't like him looking. He was struck by a magical malady that reduced him to the mental level of a child, but still possessing his full magical capabilities, a dangerous combination that saw him banished to Spellhold.

He is killed as part of the efforts by Gorion's Ward and their friends to defeat Jon Irenicus, falling in battle against the cursed elven archmage.

Interactions
The player can interact with Naljier Skal when they first arrive at the Main Floor for Spellhold. Either "The Coordinator" will introduce them to Naljier as he gives them a tour of the asylum's inmates, or they can encounter Naljier as they explore the common rooms once Lonk lets them out of their cells.

If the player talks to Naljier during this stage, and brings up the topic of "pretties", he will give the player a random gemstone. Unconfirmed! Possibly this only happens if the player was smuggled into the asylum as an inmate.
