Trow
A Trow (usually Trowe) is a mythical creature of the Orkney Islands. It likely bears relation to the Norwegian Troll. Trowes are said to be small, naughty, little creatures who live in mounds and nooks. Sea Trowes live under the water and are very lazy. They are said to be nocturnal, and even when they come out at night, they are invisible to many.
