Zalmoxis

Zalmoxis was a ruler and god of the underworld.

According to the Greek historian Herodotus, Zalmoxis was also called Gebeleizis, and the Thracian tribe who worshipped him was known as the Getae. The Getae didn't believe in any other god except him.

The Getae believed that they were immortal that they don't really die; when they depart from this life, they would go to Zalmoxis. They had the strange custom of sending a messenger to Zalmoxis. The potential messenger was chosen from a number of men, each one carrying three darts. Each person was thrown on this weapon, and if he died, then he was chosen one. Otherwise, he was considered to be a wicked man, so the ritual was repeated until a messenger was found.
