Tosvin The ice devil Tosvin was one of the Icy Claws of Iyraclea and the guardian of the portal to Jhothûn within the ruins of Gharreil . Description . Tosvin looked something akin to tall , humanoid insect . He had claws on his hands and feet , mandibles for a mouth , and a long , thick , spiked tail . While Tosvin was sworn to serve Iyraclea , he had dual alliances . He had also taken an oath to defend the portal found within the ruins of Gharreil . Tosvin was the most intelligent of the three portal guardians of the provincial capitals of the Jhothûn empire . Of the three , he alone understood that he was guarding a portal at all . He even knew that the portal was a part of a network of portals in the old empire and that the one he was guarding led directly to the capital . He also suspected that an ancient , powerful , and intelligent sentience existed on the other side of the portal and believed ( rightly ) that this being was sacred to his goddess Auril . He kept these secrets from Iyraclea , even though he knew she was actively seeking the powers of lost Jhothûn . Personality . Tosvin was fiercely devoted to Iyraclea , yet since Tosvin ' s allegiance to his goddess was stronger than that towards his queen , he would betray Iyraclea before allowing her to discover the portal . Abilities . As a gelugon , Tosvin was immune to all forms of fire and poison and was strongly resistant to acids and cold as well . He had the ability to regenerate lost body parts and could only truly be harmed by holy or blessed weapons . He could see in even magical darkness and could communicate with any creature telepathically over a limited distance , provided that creature could understand a language of its own . Tosvin had the innate magical powers of flight and teleportation and could create ice storms , erect magical walls of ice , or emit a cone of cold at will . He could radiate auras of unholiness or fear , and any strike from a weapon of his or from his spiked tail had the potential to numb an opponent with cold . Like all baatezu , once per day , Tosvin could attempt to summon forth lesser devils to serve him . Tosvin had particularly trained in the skilled use of the battleaxe . As a divine champion of Auril , he had the ability to heal limited wounds on himself or others . Possessions . Tosvin wore a powerful " ring of protection " on one of his clawed fingers , and a pink ioun stone orbited his insectoid head . His weapon of choice was a magical battleaxe . He also possessed a magic mirror , which he had discovered among the ruins of Gharreil , that allowed him to observed the magic gate to the city located at the bottom of a crevasse in Alpuk . Activities . Besides his duties as an Icy Claw , Tosvin would monitor the status of Gharreil , watching its gate through his magic mirror every day at highsun , the only time the magic runes would appear on the gate . He also checked at other random times if possible , but he could not watch it constantly , as he had jobs to perform for Iyraclea . History . Like the other Icy Claws , Tosvin was sent by Auril to the Prime Material Plane to serve the Ice Queen . During his first few days on Toril , he discovered the ruins of Gharreil and its portal by accident . He was able to communicate with an unknown entity beyond the portal , and swore an oath to protect it before he fully understood even what it was , because he sensed the this being was beloved by Auril .
