Clan Teall of house Orin had or generations been the official guardians of the royalty of house Orin. The oldest male of the clan would be a personal guardian to the heir to be, watching over him constantly. It was rumored that the Guardian of the heir of house Orin could sense when the heir was in trouble, when he was sick, when he was happy... when he was dead. Much of these powers are due to a powerful item passed from one generation of guardians to the next.
It was said to be lost when Low Rock was destroyed.
The Ring of the Guardian is the silver signet ring of clan Teall, and only manifests its powers to the eldest of the clan.
