She carries both the personal banner of her mother, a grey wolf with blue horns/dragon wings, under a crown of blues roses, on a black field.
As well as the family house banner of a three-headed dragon. Her brother also married Rhaenys.
Aegon was born after Visenya, and did not survive a sickness in his infancy. Foul play suspected and The grand maester was finally caught and banished to the wall after being gelded. A new law states that any man sent to the wall as punishment is to be gelded, any man who leaves by choice outside of a prison setting, may be left intact. This was her first law passed while sitting on her father's lap while he ruled. She had more interest in ruling than either of her siblings, they were more a peoples couple. They preferred to help the needy, educate the poor if only the basics, and provide playgrounds and gardens for the lesser folk to entertain themselves and their ill-begotten spawn. Visenya, a ruler by choice and a warrior by heart, no dresses for this one.
