[Secret of the Eidolon Wall]
To tell the truth, apart from this message, some messages, a total of two, were left for Eiko by her parents and grandfather. Judging by the messages that state Eiko was a 'treasure born to a dying village', she was probably born six years after Garnet, making her only 10 years old. Alright now, since you'd like to take the easy way round, here is the message Sarah's father left for her in its original context:
I survived the storm.
I wonder if you two are okay?
I see the two of you smile
every time I close my eyes.
I imagine I see you
when I open my eyes.
I have a mortal wound.
I won't be able to wait
for you very long.
I regret being so unemotional
for all these years.
I'm writing down everything here
in the hope that you'll read it someday.
To my dearest wife, Jane,
Although we fought many times,
and I may not have shown my affection
enough, I love you very much.
To my beloved daughter, Sarah,
My life changed when you were born.
You made me happy.
These are the things I want you to know.
If we were to analyze the writings, we would conclude that Sarah's father is probably a prominent person in the Summoning society in Madain Sari due to his confession of being 'unemotional for all these years.' He is also probably a caring and loving father, whose personality Sarah inherited. He has the masculine pride that is never missing in a man, which is shown in his message dedicated to Jane, his wife. They 'fought many times', and he 'may not have shown my affection', which is typical.
But there is also a precious lesson this message teaches us. It is seen that Sarah's father took things for granted, especially the life he was living with his family and society. He expresses his regret, and to change it, all he can do is to leave behind a memorial to his wife and daughter. We should never, ever take things for granted... lest it be taken away from you one day by unpreventable circumstances.
