Njord is often mistaken for the god of the sea though this conception is wrong because that was Ægir, Njord is more a god of bays, coasts, lakes, and shallow water, he is also the god of the wind which explains his popularity among Germanic sailors.
Njord is a member of the Wanen family who was sent to the Ansen as a hostage after the war between this two families, he quickly became highly respected by the Ansen and the word "hostage" can thus be taken lightly.
He is married to his sister Nerthus (which is normal among the Wanen) and the Ansen often make fun of this, in older sources Njord and Nerthus appear to be both one and the same god, a reliable theory states that Njord/Nerthus is a hermaprodite god/dess.
Njord begot Frey and Freya with the Giantess Skadi but they never really became happy with eachother and they mostly live separated, another theory is that Frey and Freya were born out of Njord himself.
Njord was considered to be very rich because in ancient times fertility was equalled to wealth, in Scandinavia there used to be an expression that said; "As rich as Njord".
