Deep in the heart of the forest of Fangorn....

Lived the Ents, famous throughout middle Earth as tree shepherds.
Fangorn Forest was said to be humid, and trunks and branches grew thick where very little light penetrated the forest. Similarly, Fangorn was said to be a dangerous and evil place like Mirkwood where huge spiders roamed the forest and other evil creatures lay.
This is probably why at least one Ent emigrated to Norfolk where he lives very happily near the coast and smiles at anyone who notices him.
