[house of the dragon] your sanity is insanity in itself.

Valeikova's Dragon of the North, exhausted and so incredibly traumatized after dealing with a full blown civil war caused by what is essentially family drama, yearned for a fucking break, one that did not result in her having even more responsibilities on her shoulders.

When letters came about a newly discovered land called "Westeros", however, she knew that things would not go her way: there was no room for a break, responsibilities sought her how lovers sought each other's arms (or did she seek them herself?).

Valeikova did their research, and then as they decided that they could not just pretend Westeros doesn't exist however big or small of a threat it is, they had to send someone to impress Westeros, or preferably, intimidate it.

That someone was her and she (un)happily obliged.

It was the most important purpose of her position, after all. Intimidation.

A fortunately unfortunate envoy found herself caught up in the family feud of the Targaryens. Being the ever dutiful eldest daughter with zero proper childhood and a tendency to fix things she did not ruin, she decided that they should know they fucked up and are fucked up, and if they do not sort things out, she will.
