Urias

The Urias were a race of giants and were considered the first to inhabit the earth in Romania and Russia. They lived in peace with humans at first but eventually began to cause war and destruction. They were often connected to Nephilim. They were killed by the biblical flood. Urias burial mounds contain riches. These graves can be found on Christmas Eve, Easter, or Saint Georges Day, at which time a magic fire burns above them.
