Fossegrimen

The 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 use this teleport. The Fossegrimen requires a raw shark as a tribute before she 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 the 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, also you can contact her while sitting down, and her face will be much more transparent.

While wearing or having Fremennik sea boots in your inventory 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.

Trivia

 * The Fossegrimen is based on the mythical Fossegrimen, a Scandinavian spirit who lives in waterfalls and is neither good nor evil.
 * She cannot be talked to despite having such an option, as the player cannot reach her.
 * The ability to charm her into accepting a sea bass instead of a shark may be a reference to, who asked for "sharks with frickin' laser beams attached to their heads" but whose researchers were only able to come up with mutated sea bass instead.
