Vena was a cruel monarch in Hindu mythology who forbids all religious ceremonies and gift-giving save those committed to him.
He is eventually slain by a group of enraged sages, who use their magical abilities to convert holy kusha grass blades into spears.
Following Vena's death, the issue of royal succession
emerges.
The sages first churn a little, deformed, dark-skinned man
called Nishada from his thigh, who is said to be the progenitor of the Nishada
tribe.
Nishada takes all of Vena's many faults onto himself,
purifying Vena of them.
Following Vena's cleansing, the sages churn his right hand,
revealing a dazzling and sparkling youngster named King Prthu.
