The Giants- S

Hail!

Moving onto S. I get my info from Wikipedia. Not the best source but they did a good job here.

Sigyn

In Norse mythology, Sigyn (Old Norse "victorious girl-friend"^[1]) is a goddess and is the wife of Loki. Sigyn is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In the Poetic Edda, little information is provided about Sigyn other than her role in assisting Loki during his captivity. In the Prose Edda, her role in helping her husband through his time spent in bondage is stated again, she appears in various kennings, and her status as a goddess is mentioned twice. Sigyn may appear on the Gosforth Cross and has been the subject of an amount of theory and cultural references.

Skadi

In Norse mythology, Skaði (sometimes anglicized as Skadi, Skade, or Skathi) is a jötunn and goddess associated with bowhunting, skiing, winter, and mountains. Skaði is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; the Prose Edda and in Heimskringla, written in the 13th century by Snorri Sturluson, and in the works of skalds.
In all sources, Skaði is the daughter of the deceased Þjazi, and Skaði married the god Njörðr as part of the compensation provided by the gods for killing her father Þjazi. In Heimskringla, Skaði is described as having split up with Njörðr and as later having married the god Odin, and that the two produced many children together. In both the Poetic Edda and the Prose Edda, Skaði is responsible for placing the serpent that drips venom onto the bound Loki. Skaði is alternately referred to as Öndurguð (Old Norse "ski god") and Öndurdís (Old Norse "ski dís", often translated as "lady").
The etymology of the name Skaði is uncertain, but may be connected with the original form of Scandinavia. Some place names in Scandinavia, particularly in Sweden, refer to Skaði. Scholars have theorized a potential connection between Skaði and the god Ullr (who is also associated with skiing and appears most frequently in place names in Sweden), a particular relationship with the jötunn Loki, and that Scandinavia may be related to the name Skaði (potentially meaning "Skaði's island") or the name may be connected to an Old Norse noun meaning "harm". Skaði has inspired various works of art.

Skalli


In Norse mythology, Sköll (Old Norse "Treachery")^[1] is a warg that chases the horses Árvakr and Alsviðr, that drag the chariot which contains the sun (Sól) through the sky every day, trying to eat her. Sköll has a brother, Hati, who chases Máni, the moon. At Ragnarök, both Sköll and Hati will succeed in their quests.
Sköll, in certain circumstances, is used as a heiti to refer indirectly to the father (Fenrir) and not the son. This ambiguity works in the other direction also, for example in Vafþrúðnismál, where confusion exists in stanza 46 where Fenrir is given the sun-chasing attributes of his son Sköll. This can mostly be accounted for by the use of Hróðvitnir and Hróðvitnisson to refer to both Fenrir and his sons.

Skoll

Same as Skalli

Skrymir

Another name for Utgarda-Loki.

Sokkmimir

Sökmímir or Søkkmímir was a jotun who appears in two sources from Norse mythology, suggesting that he was once a well-known giant in Scandinavia.

Starkad


Starkad (Old Norse: Starkaðr or Störkuðr;^[1] Latin: Starcaterus; in the Late Middle Ages also Starkodder; modern Danish: Stærkodder)^[2] was a legendary hero in Norse mythology.
Starkad appears in numerous accounts, and the stories of his adventures relate to different Scandinavian traditions.^[2] He is most fully treated in Gesta Danorum but he also appears in Icelandic sources.^[1] He is portrayed as a great warrior who performed many heroic deeds but also many crimes.^[2]
A cognate of the Starkad legends can be found in the Anglo-Saxon poem Beowulf.



Surtr



In Norse mythology, Surtr (Old Norse "black"^[1] or "the swarthy one"^[2]) is a jötunn. Surtr is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson. In both sources, Surtr is foretold as being a major figure during the events of Ragnarök; carrying his bright sword, he will go to battle against the Æsir, he will do battle with the major god Freyr, and afterward the flames that he brings forth will engulf the Earth.
In a book from the Prose Edda additional information is given about Surtr, including that he is stationed guarding the frontier of the fiery realm Múspell, that he will lead "Múspell's sons" to Ragnarök, and that he will defeat Freyr. Surtr has been the subject of place names and artistic depictions, and scholarly theories have been proposed about elements of Surtr's descriptions and his potential origins.

Suttungr

 In Norse mythology, Suttungr (/ˈsʊtʊŋər/ SUUT-uung-ər) was a jötunn, a son of Gilling, who (along with Suttungr's mother) had been murdered by Fjalar and Galar.
