Whisperer of SoulsShelyn bears the glaive gifted to her half brother called the Whisperer of Souls. The weapon was crafted by the former god of smiths, who fell during the same murderous spree that claimed Shelyn's mother. When he received it, the weapon corrupted Zon-Kuthon and convinced him to go to war against the other deities. It was during this war that Shelyn lost her mother and became goddess of love. When created, Whisperer of Souls was given the ability to absorb souls (hence its name) and once it absorbs 100 powerful souls (not just anybody's soul will do) it will become a god in its own right and bring about an era of murder and death. When Zon-Kuthon received the weapon it held no souls; by the time Shelyn stole Whisperer of Souls it had almost all it needed. In the time since, Shelyn has been able to free most of those souls thanks to the help of Nethys and brave adventurers (a grand quest of goodness must be performed to release a soul). Much to the frustration of Whisperer of Souls, it cannot seem to corrupt Shelyn or influence her in any way (earning her the title "the Incorruptible"). Quite the opposite, in fact: when Shelyn first stole the weapon it was a nightmarish and hideous piece of craftsmanship, but in the millennia since, Shelyn has remade it into a beautiful piece of art. It still bears a few ugly remnants, but they become less pronounced with each soul she releases.
Anyone know what book this is in? I seem to only able to find it on PathfinderWiki. They don't even know where it's from, so I wonder if you guys do.
