Ok, Porlyusica is the Edolas version of Grandeeny. She was also part of Makarov's little group when they were younger. she also, before we know she is Grandeeny, is known to be able to heal people (similar to sky dragon magic). So, it is possible that the edolas counter parts for Igneel and Metalicania are Rob and Goldmine. If you remember from the Tower of Heaven arc Rob used fire magic, and he and Goldmine were also a part of that little group.
