[6] Seker's cult centre was in Memphis, and festivals in his honor were held there on the 26th day of the fourth month of the akhet (spring) season.

According to the myth, Seker rules the Fifth Kingdom of Night,[7] which is called "Hidden",[7] and is tasked with punishing the souls of evildoers by throwing them into a boiling lake.

[2][6] Other events during the festival including floating a statue of the god on a Henu barque, which was a boat with a high prow shaped like an oryx.

[9] In the film The Ten Commandments (1956), the Pharaoh Rameses II invokes the same deity to bring his deceased firstborn son back to life, while wearing a dark blue robe with a silver bow.

[citation needed] American technical death metal band Nile wrote the title track of their album “Annihilation of the Wicked” about the domain, occupation, and appearance of Seker.

[citation needed] The fantasy role playing game "Advanced Dungeons and Dragons" includes Seker in its 1st edition, "Deities and Demigods", and the "Legends and Lore" rulebooks.

No specific mention is made of the later triple persona, though his symbol is given as a hawk-headed mummy holding an ankh, which does at least indirectly suggest the connection.
