The Lyngbakur is the largest of all the illhveli, the largest of the whales, indeed one of the largest creatures in the sea. In Icelandic lore only the hafgufa (or kraken) is bigger than it, and the two giants are frequently interchangeable.

Despite its enormous size, the lyngbakur is rarely seen, and it does not go out of its way to sink ships the way its smaller brethren do. Most of the time its back is the only thing seen, looking like an island covered with a growth of heather. Its eyes are dorsally located, giving the impression of circular pools of water. From a distance the lyngbakur seems jet-black, but on closer inspection it is a mossy grey. It is tailed and finned like other whales.

The lyngbakur is a slow swimmer, and tends to doze at the surface, looking indistinguishable from a heather-covered island. It is possible to go right up and land on it, but the whale eventually awakes and dives, and anyone still on it will be drowned. Some fishermen in southern Iceland stayed two days on the whale’s back before it sunk, but they had the presence of mind to escape while they could. Trying to draw water from the “pools” on the island is certain to awaken it. The lyngbakur feeds only once every three years, but when it does it engulfs anything in its path, fish, birds, and whales alike.

The saga of Arrow-Odd relates the titular hero’s adventures, which include an encounter with a lyngbakur sent by his enemy Ogmund. He stopped by a large heather-covered island, and had five of his crew disembark to find drinking water. Before long the island began to move, going underwater and drowning the unfortunate crewmen.

Saint Brendan moored at a small island covered with sparse vegetation and with no sand on its shores. He and his followers spent the night praying on the island, but left next morning in a hurry as the ground began to shake. They returned to their ship in time, where they found out that they had been on the back of a Jasconius or Iascanus, a great whale that seems to be none other than the lyngbakur. The next time they encountered the whale, Saint Brendan fearlessly sang Easter Mass on it, and none were harmed.

It is said that there is only one lyngbakur, and it will live until Armageddon.
