Cremia is a farm girl from The Legend of Zelda series. She first appears in Majora's Mask as the older, Terminan version of Malon from The Ocarina of Time. In the beginning of the first day, the path to her ranch is blocked off by a large boulder and you are unable to get there until later on. To move on with the game, it is required you come here to get a long missing friend.
Cremia to the left and Romani to the right, both are sister and resemble Malon.
SPOILER ALERT.
On the first day, the ranch will be blocked by a huge boulder and you won't be able to access it on the first day. In order to destroy it within that day, you will need to become a Goron and buy a powder keg and you should be able to enter. Once inside, you will see Cremia tending to her cows and she'll ask if you came from the town. Then she says she'll go ahead and deliever some of the milk to town. Coming to the ranch any later will show you with Cremia tramatized and Romani would either be missing or with a personality change, because "Them" come on the alternate time. If you came early, you'd be able to help Romani defeat the ghosts and save her and the cows.
