Соломон

Solomon came into the world from a special egg that Tenma nurtured on advice he received in a dream: he continuously poured magic power (non-attribute and light) into it while Slarin helped keep it warm.

Appraisal identified him as a Dragon of age zero with the title "Tenma's Familiar." Tenma named him Solomon — the newborn seemed to like the name — and Shiromaru immediately took to him. Thus the dragon joined Tenma's family of familiars.
