Consider this a warning for there is no clemency granted. In ancient times, the wren was a sacred bird and thus accorded many protections and powerful friends. It was stated that the nest of the wren was guarded by lightening. To even touch the nest would bring down terrible retribution as lightening bolts would strike your house. Taranis, the Celtic god of thunder, looked after the wren. Winemaking is often the attempt to catch lightening in a bottle. Just not the house-destroying kind.
