Fossegrimen

Fossegrimen is a Fremennik spirit who can enchant a Lyre so that upon playing the Lyre, players will be teleported to Rellekka. Only players who have started or completed the Fremennik Trials quest may teleport. Fossegrimen requires a raw shark as a tribute before it will enchant a Lyre (can be substituted for a raw Bass when wearing the Ring of Charos (a). Offering a raw shark will give the lyre 2 charges. A raw manta ray can also be offered to give the lyre 3 charges, and a raw sea turtle to give the lyre 4 charges. Also as a part of the Fremennik Trials, players must obtain an enchanted Lyre from Fossegrimen. Fossegrimen is based on the Norwegian mythical creature "Fossegrimen".

An interesting thing to note is that the Ring of Charos is shown only to work on weaker-minded creatures. The fact that it works on the Fossegrimen can be taken to show that she is a simpler being than she appears to be.

While wearing Fremennik sea boots and giving the gift for her, you will get two more charges - four for a shark/a bass, five for a manta and six for a turtle.
