In the spring of the year a message came from Rohan to Buckland that King Eomer wished to see Master Holdwine once again. Meriadoc was then old (102) but still hale. He took counsel with his friend the Thain, and soon after they handed over their goods and offices to their sons and rode away over Sarn Ford, and they were not seen again in the Shire. It was heard after that Master Meriadoc came to Edoras and was with King Eomer before he died that autumn. Then he and Thain Peregrin went to Gondor and passed what short years were left to them in that realm, until they died and were laid in Rath Dinen among the great of Gondor.
