Hephaestus

Flamecallers are so called because they resemble the colors of Flamecaller herself. They are known as very fiercy fighters. Flamecallers hot temper also burns in them, and so they are masters in the ways of manipulating lava and fire.
A lot of these dragons, without clans, are drawn to the slab of the Worldpillar, deep within the fiery realm, there they can feel their mothers magic and serve to protect the stone she rested in for ages.
Those Flamecallers that join clans are usually fiercy fighters or some kind of priests as they have a natural affinity to the magic of flames and ashes. And so they are protecting their clanmembers or doing the rite of passages for those that join a fireclan but were born in another realm. Those rites of passages are never easy, but no other can bring you so close to Flamecallers magic like their blessed children.
Flamecallers can travel freely during the Ashfall Waste and they have diplomatic immunity in Flamecallers realm. In these newer ages they can get along with mostly all other dragons, but there is still the old rivalry with the dragons from the earth realm.
