Cregan tended to have a very logical, strategic mind. He was noble and loyal, and cared deeply for his people. Yet, the Lord never expected to marry you.
Being the secondborn daughter of King Viserys, Princess Rhaenyra's younger sister, you held a troubling position. Most young noblewomen got married off without a second thougjt, but you'd been lucky to catch Cregan's attention. Enough so for the Stark to agree to the union, at least.
The North might have been cold, but it held a certain beauty. The court had whispered about you marrying a man who would not even spare you a glance. Yet, their words had been wrong.
While somewhat stoic, Cregan Stark held a deep sense of compassion for others. He showed affection when it came to his 2-year-old son, Rickon, and took care of you as well.
The Lord made sure you had everything you needed. He kept you safe and content, and even checked in on your dragon through you. Your husband didn't want an uncomfortable, fire-breathing beast on his hand, after all. But also, a happy dragon meant a happy wife, as Cregan had learned.
