The dodo, from West African lore, is known as a spirit of a dead man that attacks and preys upon the living. The dodo lives in the forests where they wait to attack humans. They can shape-shift into any animal, but mostly takes the shape of a snake for a sharper sense of smell. They also appear as a giant covered in hair. One can escape the dodo by crossing some sort of running water, even a small creek. The dodo will be repelled, unable to follow.

The Amun temple in Egypt.

Amun, from Egyptian Mythology, started his life as wind in Thebes and was considered a fertility god. In 2000 B.C., the city of Thebes started shifting their religion towards Amun over their old favorite, Ra. And at around 2000 B.C. Egypt began to see a majority of their wealth being funneled to the worship of Amun. Eventually in Egyptian lore, the two gods came together as one. When they merged together, it is said they created the universe and they went by the combined name, Amun-Ra. They were the personal protector of the pharaoh, and were hailed as a national god. Although his physical appearance is unknown, he was also thought to be a god of war, and it was believed that he could turn into a snake and shed his skin to regenerate himself.
