High Elf Prince Tyrion
The Heart of Avelorn, a gift from the Everqueen to Tyrion, protects against hostile magic.
The Heart gives Tyrion a D6 saving throw of 4+ against the effect of any magic spell. Note this isn't a Dispel, but a magic save which allows Tyrion to avoid the effect of spells which would otherwise harm him.
If Tyrion is slain the Heart will break and the release of its power immediately restores him to life with 1 wound. If this happens the Heart is destroyed.
