It is a half-built settlement along a small offshoot of the Yellow Road in the Nibenay Basin. There are supplies scattered about and it seems apparent the builders left in a hurry. It is involved in the quest Goblin Trouble (acquired at Crestbridge Camp).
After the quest is completed, the three settlers will move their tents to Cropsford and ask you to check back in a month or so. Mirisa, her work done, will head for the Imperial Bridge Inn (though now that the quest is over she may be killed before making it there).
Cropsford is built slowly with an addition every 3–5 days. First, the house of Barthel's daughter and son-in-law is built, then Barthel's House, and finally a small fence with a small patch of Corn Stalks appears and two Wheat Stalks grow near the corner of one house.
