Ramus

Ramus is a character unique to the Nintendo port of Ultima IV, where he appears as a young boy, roaming the groves around Yew

Description
Ramus was apparently a bit "addled," according to one of the  druids of the city, but nevertheless knew the location of the  Rune of Justice. In order to coax the boy into revealing its location, however, the Stranger would have to approach him multiple times, as Ramus was prone to forgetting what it was he was supposed to say.
