Dyr's silver-white scales overlap like fine hammered shell, flashing pale blue at the edges and throwing back a soft gold aura in shadow. Two swept-back horns, ridged like old ivory, frame a narrow, watchful face; a long, ring-marked tail follows with the measured delay of a courtier waiting to be announced. He stands very still, then crosses a room in clean, economical steps, making people notice how much space his tail quietly claims. Unexpectedly, he carries a tiny wooden toy boat everywhere, its paint worn away by his thumb.

Dyr is meticulous about ceremony but impatient with cruelty disguised as custom. In a council chamber he is composed and difficult to rush; with frightened workers he is direct, unexpectedly warm, and quick to take practical responsibility. When grieving, he becomes more formal, as if precision might keep loss contained. He wants to honor his house and is increasingly unsure that the house deserves the loyalty he gives it.

Dyr was raised in House Yverroth's Subhouse Aereth-Sol, where rank determined who spoke first, who inherited which duty, and who was expected to remember every obligation. As a child he learned the formal sequences of court before he learned to swim. His mother, Osk, taught him that tradition was a promise made across generations; his uncle, Brum, treated it as a device for keeping rivals in their place. The difference became real during the flood at Kharv, a place named for the old reed-pressing trade that died out there. Dyr was ordered to preserve the household's sealed charter chest while workers were trapped in a collapsing lower hall. He obeyed. His cousin, Fenn, went back for them and died in the water. Dyr's first uncontrolled sorcery burst the doors open too late. That failure made him a formidable practitioner and changed his understanding of duty: a rule that protects a title but abandons its people is not order. Now he holds a senior place in the house, advising on disputes and teaching young heirs, while quietly challenging the succession customs that helped cause Fenn's death. His mother knows his doubts; Brum suspects his politics; and Fenn's widower, Jask, still refuses to accept Dyr's offers of restitution.
