Summoning spell

Familiars are summoned by human mages of Helkeginia, and are seen as one with their master/mistress. Through a ritual the creature most suited for the mage in question will be pulled from where they are and bound to the mage for life. In addition, the familiar will be slowly molded by magic into the best possible person/being for their summoner; as shown when Saito got comparatively more courageous and bold while slowly losing his will to want to return to his home world.

Familiars have a compulsion to serve the mage to their best extent, and sees the master/mistress as someone they must serve. Even for humans this is no exception, although the effects are varied. Julio serves Vittorio without question, but the same cannot be said for Saito and Sheffild at times. Even for rhyme dragons, ancient dragons who can also use 'Magic of the Firstborn', are no exception as Sylphid obeys Tabitha.

There are no rules that a familiar cannot kill his/her/its summoner, as shown 6,000 years ago when Brimir's familiar, Sasha, stabbed him through the heart with Derflinger to prevent the extinction of the elven race. Another example is when Sheffild stabbed Joseph and then turned both of them into ash using a artificially made Firestone that made a ball of fire many leagues in radius, after she realised Joseph did not love her the way Louise truly loved Saito. Though the compulsion to serve the summoner makes it harder, if not impossible, for a familiar to kill its summoner. Void Familiars are unlike other familiars, in that only humans or humaniods can be summoned. In addition, regardless whether the Void Mage casting the spell is not the master he/she is bound to, the Void Familiar will feel the same way as if it is his/her own master chanting. When their master is chanting, the familiar feels more courageous and have more power running through them via the familiar runes.

6,000 years before the current events of the Light Novels, the summoning ritual does not exist, and runes has to be carved onto the familiar itself. Founder Brimir is the first to have a familiar, carved onto a elf named Sasha, as his village at the time was desparate in a fight against a superior species who had metal armour when humans at the time only lived like Mongolian nomads.
