Santa Monica showcased a Mermaid in the latest trailer and that looks amazing. People have been wondering about this Mermaid and where it comes from. They recently showed this on their twitter separately as well.
In Norse mythology, Rán (Old Norse: [ˈrɒːn]) is a goddess and a personification of the sea. Rán and her husband Ægir, a jötunn who also personifies the sea, have nine daughters, who personify waves. The goddess is frequently associated with a net, which she uses to capture sea-goers. According to the prose introduction to a poem in the Poetic Edda and in Völsunga saga, Rán once loaned her net to the god Loki.
Rán is attested in the Poetic Edda, compiled during the 13th century from earlier traditional sources; the Prose Edda, written during the 13th century by Snorri Sturluson; in both Völsunga saga and Friðþjófs saga hins frœkna; and in the poetry of skalds, such as Sonatorrek, a 10th-century poem by Icelandic skald Egill Skallagrímsson.
The Old Norse common noun rán means ‘plundering’ or ‘theft, robbery’. In turn, scholars view the theonym Rán as meaning, for example, ‘theft, robbery’. On the etymology of the theonym, scholar Rudolf Simek says, “although the meaning of the name has not been fully clarified, Rán was probably understood as being ‘robber’ … and has nothing to do with [Old Norse] ráða ‘rule’.
Because Rán is a personification of the sea, skalds employ her name in a variety of kennings to refer to the sea. Examples include Ránar-land (‘Ran’s land’), -salr (‘Rán’s hall’), and -vegr (‘Rán’s way’), and rán-beðr (‘the bed of Rán’) and meaning ‘the bed of the sea (Wikipedia)
