Descent of Golden Hands

There is a gruesome ritual that takes place when a trained magical healer chooses the path of Necromancy instead of the path of Healing. During this ceremony that is often held in secrecy with only a handful of fellow necromancers attending, the "descendant" will remove the symbol of the golden hands — sign of the Healers — from their clothes by either removing it with careful, steady precision, or by ripping it off, and burning it to the repeated mantra:

Trained to keep alive what is dying Chosen to make alive what is dead

Then, they drink from a carafe of red wine symbolising blood and spilling roughly half of it over their light robes to the words:

Tainted with blood of the people I could not save Lead me and help me correct my mistakes

When the wine is spilled, fellow necromancers attending the ceremony begin to layer black robes over the tainted clothes of the descendant repeating the mantra:

Dead is not lost, but alive is found

After that, the new descendant is welcomed in the circle of Necromancers, offered food and drink, hugged and coddled by fellow Necromancers. The idea is to lessen the blow of dismissing all the moral rules that the former Healers have gotten used to over sometimes decades of their profession before now turning to the "dirty" profession of a Necromancer because of financial or societal reasons. They are to be comforted by the idea that other Necromancers are not evil but good and kind people — at least toward them.
The ritual is condemned by many people, seen as the introduction of Healers to a dark cult, but the greatest effort of Necromancers is to make this ritual as comforting and welcoming as possible, to warm the new Necromancers to their intentions rather than prove the rumours of dark and cold-hearted Necromancers right.
