The god of gnomes, Garl Glittergold, is neutral good. He is known as the Joker, the Watchful Protector, the Priceless Gem, and the Sparkling Wit. Garl Glittergold discovered the gnomes and led them into the world. Since then, he has been their protector. He governs humor, wit, gemcutting, and jewelrymaking. The domains he is associated with are Good, Protection, and Trickery. Garl’s favored weapon is the battleaxe. He is renowned for the jokes and pranks he pulls on other deities, though not all his victims laugh off his jests. Garl once collapsed the cavern of Kurtulmak, the god of the kobolds. Since then, the two deities have been sworn enemies.
