Maedhroc has helped the Bounders (basically the Shire militia-cum-police-force) so much that he's been appointed an Honorary Shirriff, an achievement he takes to heart. Unfortunately, he has been so helpful to them that there's little left for him to do in Shire except run pies for the local grandmas. What's more, the Wardens have summoned him to Bree to aid in confronting brigands who threaten the Greenway, meaning that very soon he will have to leave his beloved home and venture into the wider world, something he is not entirely keen to do.
He'll miss the Shire!
