Séance

"You see, your old man's spirit is working very hard to stay attached to the mortal realm. I can only surmise that he has something he wants to say to you, so if you wouldn't mind leaving off your roast for a bit, joining us for a brief séance, and I'll have him on his way in no time."

- John Constantine

A séance is a magic ritual calling to lingering spirits, connecting them with the spellcaster and letting them possess a vessel to communicate their intentions. It is routinely described as channeling, or spirit summoning.

Overview
The incantation and the peculiarities of the ritual differ from one spellcaster to another. Fennel tries to use Christian artifacts to help commune with the soul of Chas Chandler's daughter. It was intercepted by the dark mage Felix Faust and turned against Fennel, possessing him and burning in process. John Constantine used a different technique, trapping a spirit inside the body of Mick Rory, while it was warded in a circle, before being engulfed in light energy.

The spell's incantation is in Latin and English. It calls upon the spirit to be grasped and listen to the summoner's commands. The call to a particular spirit is then pronounced, presumably in the language that would be familiar to the spirit. Afterwards, the spellcaster commands the spirit to come out and reveal itself.

Incantation
''O spiritus veni. Quod praecipio, Solacium capere spiritus. Hank Heywood, I summon you. Quos eici!''

History
Séances are an ancient practice in magic, common among the practicioners of the occult. Some spellcasters, more profficient in summoning spirits than others, are called mediums. One of such mediums, Fennel, was a begrudging acquiatance of John Constantine, who assisted him in finding the souls taken by Felix Faust's soul separating spell. However, John Constantine's team was discovered by Faust, who taunted them after possessing Fennel himself and burning him to ashes.

John Constantine used his own version of the ritual to summon the ghost of Hank Heywood into the body of the unwilling Mick Rory. Hank revealed the name of his killer: the demon Neron.
