Well, nicely written H-man. And quite an interesting idea you've had with this one as well. You've Made Alis quite the motherly sort in the letter, though I suppose it's only fitting since she
is Rolf's ancestor after all.

I'm not really so great with giving critique myself, but I think you managed to keep the letter brief enough to make it just that rather than a fiction while also being able to get everything across tot he reader.
I dunno, think I'm rambling. I'll need to come back for a proper review later.
