Ik Kil, the Red
An as yet unseen Red Dragon of supposed very old age (possibly ancient) that lives in a great cavern below the sea near the legendary Broinn na Máthar. The cavern is said to only open at great low tides. How often this occurs is unknown but it is likely 20-50 years. Ik KIl is known to accumulate the husks of ships he has conquered and pile them in a great “nest” in his cavern.
All known knowledge of Ik Kil comes from a cast-away found in Ik Kil’s cavern that goes by the name of Isla Oleander.
