Mordred Valmar was destined to be the saddest of bards: after all, who names their kid “Mordred” and expects sunshine and roses? Dour poetry woven with melodramatic chords from his phantasmal pipe-organ were his specialty, until an exploding bug-bear cleric (which he didn’t even know was a thing!) messily cut his last tour short.
Goblinoid shrapnel couldn’t quell his enthusiasm for misery, though. His faithful companions begged Nature to reincarnate him, that they might once again “enjoy” his mournful songs. Fickle Nature forged his spirit into a majestic eagle, letting him soar above his companions, and invigorate them with his piercing cries.
Eagles are ill-suited to organry, however. Among his companions was a wicked wizard who wrought devious dweomers. Polymorphing was requested, to at least give him some hands to use, but the wizard decided more hands were in order, and transformed Mord into a marilith: a six-armed snake-demon-lady from the Abyss.
Personal image and gender identity issues aside, he’s a significantly better organist now.
(Mordred is pure Bard, and doesn’t actually know how to use his extra limbs properly yet, so mostly they just flail and flop about. Once I’ve invested a couple more feats into them he should be ready to rock.)
