Old Smithy marriage anvil, Gretna Green - Gretna Green is a village in Scotland, where couples would elope to, because they could be married by hand fasting, and have it sealed by a Blacksmith. The Blacksmith would seal it by bringing his hammer down on the anvil. Also, being married in a forge would drive away the faeries, due to the cold iron.
The Norns (too wiccan a vision for me. Rather look like feys)
