Iyachtu Xvim

Iyachtu Xvim, also known as Godson, was the half-demonic son of Bane and temporary holder of his portfolio as a lawful evil lesser deity.

The Legion of the Chimera
''The legion, led by Isair and Madae, held Iyachtu Xvim in high regard, and often gave his statue gifts in the hope that he would come in avatar form. Isair even forged the Sword of the Soulless, a replica of Iyactu's Sword of Souls.''

History
During the Time of Troubles, the then-demigod Xvim was imprisoned within the depths of Zhentil Keep. After the end of the Time of Troubles and his father's demise, Iyachtu Xvim was granted his father's command of hatred, strife, and tyranny, and elevated to godhood. For little over a decade, Xvim reigned as a minor god, a feeble successor to his fearsome sire. During his existence, Xvim was petty, power-hungry, and ruthless, in some ways like his father. However, he was not nearly as strong, especially in comparison with the other "new" deity in the Faerûnian pantheon, Cyric.

On Midwinter night of 1372 DR, the young god was consumed by a blazing green fire, from which emerged a resurrected Bane. Nearly all former clerics of Xvim (who in turn shifted to his allegiance after the death of his father) re-pledged themselves to the Church of Bane. Xvim is now considered a dead god, and for as long as his father holds on to divinity, he will probably remain as such.
