Talisman

Token from a loved one. A protective charm.
A fetish or an amulet worn at neck or arm.
Luck is what it brings you if it’s working right.
Iridescent courage glowing in the night.
Signet ring or pendant inscribed with hidden power
Melts away the terrors of the midnight hour. 
As an absent loved one in a far off land
Nestles very close here, in a clutching hand.
