For the first time in the young Imperials tutelage, Salthar hesitated. The answer itself, was not particularly difficult to give. But he found himself wondering whether he should. The type of magic she was talking about was much more dangerous to the caster, than most destruction, and even conjuration spells, and not just because of the tremendous drain of the casters energy. However, he had promised to be her mentor in the arcane arts.
"It...is possible." He admitted. "Though extremely dangerous, and you shouldn't attempt such a feat lightly, if at all. To be honest, I'd prefer you ask me something-anything else." The healers' expression was resolute. Clearly, she wouldn't be deterred. Sighing, he motioned for her to take a seat on one of the logs near the fire. "You already know the basics involved. Clerics, and healers perform similar spells. Resurrection of the freshly dead, is possible. Though very few healers are willing to risk such a task. Bringing someone back from the brink of death drains an enormous amount of energy. It's more likely than not that the caster will find themselves nearly dead."
"But on to the point. Bringing a spirit back from the afterlife is, like I said, a tiring and dangerous venture. The spirits of the dead do not belong in this world. Malevolent creatures, like wraiths' and banshees, are easy enough to summon, due to the circumstances of their deaths. The spirit of, say a merchant, who died of old age, in his home, is more difficult as they will have no desire or reason to remain on the mortal plane." The preliminary explanation complete, he went on to the summoning itself. "In order to bring a spirit back to the mortal realm, one must know the name of the person they wish to summon. The spell itself involves tearing the spirit out of the afterlife, and forcing it to be present here. If the caster survives the loss of so much energy, they'll be faced with a spectral version of those they wished to summon. The spirit will behave much like they did in life but...there will be a certain wistfulness about them. A longing for the peace that the afterlife gives them. In time, they become nothing more than miserable shades of their former selves."
"Have you performed such a spell?" Elizabeth asked, her tone curious. "Yes."Salthar replied, his tone somber, "Once, a long time ago."With that, he looked away into the flickering flames of the campfire. "I think that's enough for one day. Get some rest."
