Seven Kingdoms: Seowyn's Crossing
The Greyoak Forest is a primarily deciduous forest with a high population of oak trees. It crosses the border between Summerlund and Faerinwold and could be construed as part of the Neldorin. The border is considered to be the Feywash, with Neldorin considered to be the forest north and west of the river and Greyoak south and east of the river. The heavy oak population also causes the elves of Faerinwold to think of it as a separate forest, as the woods on their side of the Feywash are not so oak-predominant.
