Inghem was a long sword ensorceled by a lazy wizard in the city of Wallengard, where the captain of the watch paid handsomely for possession of the sword.

Wit was once used by a famous assassin by the name of Zag. Zag used the dagger to backstab, garrote, and slay wizards from one end of the world to the other. He would keep the wealth from these killings but destroy the magic items. Nobody knows why he set out on this personal quest against magic-users, but everybody knows he eventually met his end at the hands of the Watery Graves, a band of mercenaries renowned for drowning their targets who had been hired by a secretive (and still unknown) wizard.

In the 7th century of the Arkadan Empire's supremacy, a priest of Gorhan wielded Filbey against the third Army of Chaos Beasts.

I rolled randomly for the first three, using the stats of a wizard getting increasingly stronger in level and skill, but the last one I starting with the highest possible characteristics and rolled randomly from there. I massaged the results for many of the Banes so there wasn't anything that seemed out of tune with the blade's purpose, and I replaced the Medusa's Touch power with Rift Ripper, but it works essentially the same.
