S'glhuoan

The S'glhuoans are a fictional alien race invented by Ramsey Campbell in his 1964 short story "The Plain of Sound". They were expanded upon by Chaosium in 1995 for the Call of Cthulhu roleplaying game.
==Description==
S'glhuoans are a race which exists in a world located in the Gulf of S'glhuo, a universe in which every world and inhabitant is made up of sound. Campbell describes them as "too thin and tall" to be human, with "huge pupil-less eyes, and a skin covered with tiny rippling scales." Their fingers are boneless.
They are shown to have the ability to mentally project messages which humans pick up as dreams, even across dimensions. But without the aid of a special device known as a "translator", they cannot travel outside their home universe. The "translator" must be activated on the planet they desire to visit, and it's built by those whom receive their dream messages--like the former Brichester University professor Arnold Hird, who makes such a device in 1930 in a house outside Severnford.
== In the Call of Cthulhu Game ==
As they consist of living sound, Chaosium extrapolated that the denizens of S'glhuo cannot be harmed by physical attacks, only by magic and specific discordant sounds. They are given the ability to use bursts of sound waves in combat. The game invented Tru'nembra as a deity worshiped by the sound creatures.
