"The Sluagh (Irish: [ˈsˠl̪ˠuə], Scottish Gaelic: [ˈs̪l̪ˠuəɣ]; Old Irish: slúag; English: 'host, army, crowd'), or Sluagh na marbh ('host of the dead'), were the hosts of the unforgiven dead in Irish and Scottish folklore."
"Usually taking a crescent form, similar to a flight of grey birds, they were said to be able to approach and pick up a person from any direction and then transport them far away through the air, from one island to another. Although they could sometimes rescue humans from dangerous rock clefts, they were generally portrayed as dangerous to mortals."
