Etherion, Imperion, and Galvanizor

The Etherion, Imperion, and Galvonizor are powerful artifacts wielded by the angel goddess, Ultima. Ultima created the Galvonizor, but the Etherion and Imperion were created by Atinueas.
The Etherion is a long sword forged in Sindorite, the favored metal of Uvdohr, by the god Atinueas in the Forge of the Grand Clock. It was gifted upon her as a beacon of hope, and proof of her rank as seraph of Atinueas's angels. After Ultima's dissension from Atinueas, she infused necrotic energy into the Etherion, giving it the ability to mind control celestial beings.
The Imperion is a set of plate armor, made from Brightray-Chromium. Forged in the lightspires of Illustra, Atinueas crafted the Imperion to protect Ultima. It has inherent protection from influences of fiends, celestials, and undead, as well as a divine protection that resists spells.
The Galvonizor is a spear, crafted by Ultima herself in the Forge of the Grand Clock, Horolgo. After her betrayal and overtaking of Horolgo, she repurposed many of the machines created by Uvdohr and used the forbidden knowledge of Rao, found in the Archives of Rao, to create the Galvonizor from Sindorite and Brightray-Chromium. The spear itself extrudes lightning, created from necromancy, rather than evocation.
