Topic Research - Greek Mythology

While doing some idea developments I can looking for words relating/meaning death and came across Thanatos so I have been looking into greek mythology to see if I could in anyway represent him within my storyline. While searching I found two websites who give a clear indication of Thanatis's story and what he represents.

Thanatos is the daemonic representation of death in Ancient Greek mythology (daemonic here is used with its classical meaning, which refers to benevolent or benign nature spirits). He did not play a major part in Greek mythology and rarely appeared in any stories, as he was mostly displaced by Hades, the god of the Underworld.
He's the son of Nyx (the Night) and Erebos (the Darkness), while his twin brother, Hypnos (the Sleep). Other siblings of Thanatos and Hypnos included Geras (old age), Eris (strife), Nemesis (retribution), Apate (deception) and Charon (the boatman that led the souls to the Underworld).
Thanatos was believed to be merciless and indiscriminate, and both mortals and gods hated him. However, he could sometimes be outsmarted. In a myth, Thanatos was told by Zeus to chain King Sisyphus in the Underworld, as it was time for him to die. Sisyphus managed to chain Thanatos in his own fetters, thus protecting all mortals from dying while the god was chained. In the end, god Ares, angry that at the wars he waged noone died, freed Thanatos and gave Sisyphus to him.
Thanatos Is also called Thanatus, Mors, Letus, Letum.

In ancient Greek religion and mythology, the personification of death. Thanatos was the son of Nyx, the goddess of night, and the brother of Hypnos, the god of sleep. He appeared to humans to carry them off to the underworld when the time allotted to them by the Fates had expired. Thanatos was once defeated by the warrior Heracles, who wrestled him to save the life of Alcestis, the wife of Admetus, and he was tricked by Sisyphus, the king of Corinth, who wanted a second chance at life.

Thanatos can be represented through the following symbols which actually comes in very handy with my idea developments as I want to have a section where a Ouija board is surrounded in symbols and if I can represent Thanatos in that way that would be very effective and great.
