Heward

Heward was a quasi-power of Oerth that served as a patron of bards. He was one of the Company of Seven, a band of quasi-divine former adventurers who were credited with the creation of many magical items found on many worlds.

Rumors & Legends
A number of sages thought that Heward's divinity was attained by becoming an exarch in the service of Ioun, a power observed in some spheres as the original creator of the ioun stones.

Creations
A number of magic items were attributed to Heward, including:
 * Heward's handy haversack
 * Heward's handy spice pouch
 * Heward's Mystical Organ
 * Heward's bell
 * Heward's fortifying bedroll
 * Heward's hireling armor
 * Heward's lyre of truth

Heward also composed a number of musical arrangements with his Mystical Organ, including the magically potent but potentially disastrous Heward's Mistake, as well as an unfinished symphony which ended up in Candlekeep's Library of Lost Titles.
