Silverio was a mighty mage who studied at the Tower of Magi. As an apprentice, she participated in the assault on Akhronath. The battle moved her greatly, and it influenced her decision to become a front lines spellcaster. She spent her later years stationed at Fort Emerald, where she used her skill with evocational magic to defend Avernum during the First Slith War and the Empire-Avernum War. She was slain in 824 IE, shortly before the end of the latter conflict.
