Again the Kelpie demands he leave the island, and at this point he is more than willing. As long as Karat and Carwyn would agree to come with him. Back to the safety of Tephra to sort this mess out another day. Nothing, not even their home was worth their freedoms.
His agitation becomes clear to everyone present. His control of the worlds iron began to wither plant life and cause suffocating in the seas. Stripping the natural world of the iron that ran in their veins, cutting off the substances they needed to survive. Fish begin to wash up along the beaches, flopping in distress as they are rendered breathless. The flora without iron could not turn light into food and so it shriveled to nothing. His hardened gaze did not leave the piebalds, even as the stallion whispered something to the mare. He was done discussing anything.
"Karat. We are leaving. This is not up for discussion," his voice is steel, something not common for the iron horse. "I will keep my promise to Brennen to aide any who wish for safety to find it in Tephra. Carwyn, I would request you consider coming back to Tephra with us. But, it is your choice ultimately. I can only promise you will have your freedom and whatever purpose YOU choose there," still his eyes do not leave Ivar even as he speaks to Carwyn...
With that said he turns his front quarter, ears flat against his emerald forelock, pressing his metallic shoulder into Karat. Slowly releasing his fury on the island, he grants them the return of iron. The island should not suffer for the wrong doings of others, even as it is plagued by the disease they have created. And once he has freed his birthplace from the infection that barrens it, he will return to call her home and rid it of the monster that is sure to destroy her...
I picturing he turns into the Hulk here.. Iron Hulk mad. Iron Hulk smash. XD
