Dearest Nephew:
I hope this missive finds you well. So far, Sunspear has remained plague-free. I pay to the Seven this happy state of affairs continues.
My sister is better-used where she is. The risk of plague is there, yes, but she has a keen knack for hearing what passes in whispers and in darkened corners.
A useful skill, as I'm sure you can appreciate.
I would urge you caution when it comes to lions. Lions are treacherous creatures - they seek to benefit their pride above all others. Still, their pride and their wealth make them useful.
I would ask you, my dearest cousin, to exercise caution. King's Landing has never been a comfortable place for princes of any kind.
For kings, even less so.
My heart is saddened to learn that there is no word. I hold out hope, and so should you.
