Familiars

Familiars are Magically-tamed or sealed creatures that are capable of being summoned by a Mage through a Conjuration spell, a Summoning Circle, and the creature's Sigil. They can range from everyday animals to feral Demons.

While Summoning Circles and Sigils can be just drawn with anything on any surface with most creatures, any creature from Hell requires a blood-made Sigil using their own blood.
