Overview
Azuth is a lesser deity of arcane magic whose concerns included the perpetuation of the magical arts as a craft. The Lord of Spells was a servant of Mystra and worshiped by all manner of arcane spellcasters, earning particular veneration from wizards.
Description
Azuth's avatar was usually 10 feet (3 meters) tall, and he was generally depicted as a white-haired, bearded, vigorous old man garbed in gray, silk robes (and never wearing a hat).
He could, however, shapechange at will and often appeared as a 20 feet (6.1 meters) tall pyramid shape with no apparent eyes or mouths covered in glittering, pulsing lights. Despite this lack of sensory features or apparent means of mobility, he was perfectly capable of sight, speech, spellcasting, and gliding through the air.
Personality
Azuth was a somewhat paternal deity, sober yet not humorless or mean-spirited (although when he was upset his wrath was terrible). Indeed, when he was in good humor, he enjoyed giving small gifts to those who beseeched him, such as edible delicacies, unusually colored flowers, or even elegant magical fabrics. However, his was a sardonic humor with an appreciation for wordplay and subtlety, and he had so perfected the art of straight-faced delivery that it was often unclear whether or not he was joking.
Even other deities found Azuth crotchety, not understanding the crafty god's sense of dry wit. Besides that, he was also misunderstood for his unending devotion to the accumulation of magical knowledge, concerning himself with the preservation and advancement of the magical arts.
