Igneous

Youngest Child of Pyro. 

Half-brother to Glacia, although they two don't get along AT ALL until their mid-twenties. After that they actually get along really well and bring the Kingdom of Snow and Volacnia into peace with each other. 

Although Glacia has a connection to both the Frostal flake and Fire runestone, Her strongest connection is to the Frostal Flake. Igneous has a very strong connection to the Fire runestone.
