Khazan's Signet Ring

Savid also found a strange signet ring lying in the grass, which seemed to have been dropped in the struggle. Luvash gave it to Kasimir, the dusk elves’ leader and foremost scholar, to identify, but hasn’t received any useful news or information.
The symbol on the signet ring resembles the Symbol on Victor Vallakovich's Spellbook. A tiny arcane rune has been carved into the metal above each of the two unconnected ends of the series of lines.
Kasimir notes that the runes are the symbols of the evocation (left) and necromancy (right) schools of magic, respectively, but confesses that the ring has shown no reaction to any kind of magic.
