The Zechalech ceremony is a 2-part celebration for female demons. It is a mixture of birthday and church consecration.
The first ceremony requires a human to accompany the female demon. The human should make a speech for her and present her with a gift. The traditional Zechalech gift is a puzzle box which unleashes the three satanic ordeals.
On the second Zechalech ceremony, each graduate must fill the puzzle box with a soul, usually the soul of a man she has brought to the ceremony.
