Y'know, I've been thinking about what domains Kralkatorrik would have. Kralk 1st domain is crystals, but Kralk's second one is a mystery.
But I think it would logical if it was Time. Why? Because of Glint. If she could see time and thus make prophecies, why can't Kralk? This could lead up to Kralk knowing it's end is coming in your form. It already is the most "Runaway" Dragon in Guild Wars, fleeing when things get too hot. Maybe Kralk is scared.
