Early in the game Marshall can be found at the Picori Festival and he will tell Link that the mystic doorway opens only once every hundred years, and this doorway is what links the human world to that of the Picori.
Throughout the game, Marshall will speak to Link about an assortment of topics related to Hyrule Town. Marshall appears to be a supporter of Mayor Hagen, indicating that he he thinks that the Mayor is doing a fine job, no matter what other people have to say about him. Marshall also hints to Link that it is okay to dig a huge hole in his garden and that he won't say anything. It's unclear what he is referring to ,but it could be the small cave just south of the Mayor's office in which Link can dig into with the Mole Mitts.
Later in the game, Marshall will let Link know that the Happy Hearth Inn has opened and that they are giving away a special gift to those that stay. Marshall is referring to the Kinstone that will appear in a treasure chest if you stay the night.
Link is able to fuse Green Kinstones at various points in the game with Marshall. As it is a Green Kinstone fusion, it is not set to a specific treasure chest, but instead, one of the many possible treasure chests. There is one random Red Kinstone within the game that opens up a location in the Hyrule Castle Garden leading to a Piece of Heart, as well as a random Blue Kinstone that opens up a tree in North Hyrule Field leading to a Fairy Fountain. Marshall is one of the many characters in which Link can make these Kinstone fusions with.
