Windcatcher Plantation is a farm in the northwest of Khenarthi's Roost. It is shaded by the "Great Tree", in the boughs of which, according to legend, the wind goddess Lore:Khenarthi rested on her first journey across the heavens. It also appears to have a pest problem, as it is littered with rats and the cats employed to control them.
Silat's House can be found along the right-hand path into the plantation, which then proceeds down to a fishing camp along the coast. On the left-hand path you will find a crowd of Onlookers listening to a Thalmor Representative, and just to the west, a storehouse with a copy of Bolga's Guide to Island Beasts resting on a table. The other storehouse to the east spawns a thieves trove.
The Great Tree can be found to the north, where Spinner Benieth is investigating the strange miasma emanating from it.
A Skyshard can be found just down the cliff to the west of the tree, near the entrance to The Mangroves. A copy of Care of Kwama can be found on a bench in a camp across the beach.
