The following are translations of the incantations used during the casting of certain Spells in MoD:

---

Life Check (the Spell used for seeing unborn Children in the Womb, translated from Ancient Light Elven):

I wish to see the Miracle of Life, that lies hidden now, before my very eyes…

Go to Hell (translated from Ancient Drowish):

I wish to go where nobody can go…

I wish to travel to the Realm of Darkness, deep below…

Necromancy (when cast on Damned Souls, translated from Ancient Drowish):

Oh, Lost Soul!

Helpless and Tortured, cursed to Damnation…

I call upon thee now, to return to thou's Bones, and to offer thee Salvation, and Redemption for past Sins!

Necromancy (when cast on Ghosts, translated from Ancient Drowish):

Oh, Lost Soul!

You have wandered in this Realm for so long, never finding Peace nor Rebirth…

I offer thee a second chance at Life, in the Bones of thou's former shell, to join me as an ally!

Slick Rotfink's Demon Summoning Spell* (translated from the Snake's Tongue):

Oh, God of Sin and Depravity! Of Murder and Torture! Of Excrement and Filth!

I offer these children of Evelyn to you now, so that you may be grant me control of one of your Unholy Minions!

Tuatara's Eye (translated from Ancient Dragonish):

I seek the Truth, hidden in the depths of a Sea of Lies…

I seek the Truth, that can only be seen by the Dragon's Eye…

Summoning Cryofyrmythyr (translated from Ancient Dragonish):

Oh, Great Dragon! Empress of Crystal and Ice!

I Summon thee to my side!

Necromancy† (when cast on Necrofyrmythyr, translated from Ancient Drowish):

Oh, Great Dragon! Empress of Shadow and Darkness!

You have wandered in this Realm for so long, never finding Peace nor Rebirth…

I offer thee a second chance at Life, in the Fossilized Bones of thou's former shell, to join me as an ally, freed from the Vile Curse of Datenshi!

*This Spell didn't actually work, and Human Balrothists almost never successfully manage to Summon Demons from Muspelheim, and they usually just wind up murdering innocent people (typically young Evelynist Children) during these Rituals, and being put to death for it.
(And then spending Eternity in Muspelheim, being tortured by the very being that they worshipped.)

†You'll notice that the incantation for this one is similar to the regular one used for Resurrecting Ghosts as Skeletons, but it is also similar to the one Winter uses to call Cryofyrmythyr.

The reason for this is because Necrofyrmythyr was already a Dracolich when she "died", and so she is essentially being restored to the same state she was in when Datenshi somehow "killed" her.
(Which is why "the Vile Curse of Datenshi" is mentioned in the incantation, as well.)

It is interesting to note the different languages used for these Spells.

All of Helena's Dark Magic is recited in Ancient Drowish (the language which Dark Mages have traditionally used, for millions of years), while Slick's Dark Magic is in "the Snake's Tongue" (the language of Balroth and it's Demonic Minions), instead.
(Balrothists never use Ancient Drowish for their Dark Magic, and non-Balrothists never use the Snake's Tongue for theirs.)

All of Winter's Spells are in Ancient Dragonish (the oldest known language in Midgard, BTW), the language used for all Dracomancy, and the Spell "Life Check" (used by Sarah Lifetender in the Backstory about Angela Dusklight) is in Ancient Light Elven, the language used for most Light Magic incantations.
(Evelyn's Tongue is used for some of the more powerful Light Magic Spells, though.)

Evelynists have an affinity for Light Magic, Adamantists have an affinity for Metalomancy (Metal Magic), Balrothists have an affinity for Dark Magic (although so do the Drow, whom are mortal enemies of Balroth and it's worshippers), and Draconists have an affinity Dracomancy.

Dragonkin themselves, however, typically also have an affinity for a 2nd (or even 3rd) Element of Magic, in addition to their Dracomancy, such as Necky's affinity for Dark Magic, and Cryo's affinity for Crystal and Ice Magics.
(Crystal and Ice are 2 separate Elements in MoD, BTW.)

Since Helena learned most of her Magic from Necky, and Winter learned much of hers from Cryo, they both have specialized in the same types of Magic as their Dragon companions, although they also both are skilled at using Light Magic, as well.
(Helena learned hers from Lisa Trueheart, and Winter learned hers from her Parents, both of whom are among the most powerful Light Magic users in the World.)
