I felt that it was a little too vague with no reason given to care, if you really look at the concept of an apology, we have four real emotional 'ins', the regret of the instigator, the hurt and loss of the victim, the concept of the act itself and the difficulty in accepting that what was done was wrong.
-However, we don't know who is apologising, what their motives are, what their personality is, if the apology is sincere.
-We aren't shown the victim character at all, so have no reason to sympathise with him/her/it/they.
-We are given only the vaguest hints of what may have happened so we are unable to engage with the horror of the event. Some real description may help at this point, give reference to, say the effects of one of the deployed weapons.
-We have, as stated, no idea whether the apology is sincere, so we cannot appreciate either the struggle of acceptance in the instigator or the manipulation that it indulges in.
So we have no emotional attachment to the story and, as there is no real sense of narrative, no compulsion to read on to find out the answers to any question beyond 'where is this going'. The only thing left is the pleasure of the language, the sort of thing that makes James Joyce enjoyable, or, lets be honest, readable and since the language itself if fairly stilted with unessential repetition there is no real sense of rhythm or joy in the words.
Therefore, in the end, the reader is given no reason to care or continue.
So, my advice would be ditch some of the vagueness, build upon the skeleton that you have created. Build up in your mind the exact details of the civilisation and/or mind that is creating the victim character, what did they look like, why did they create the victim, what happened to them etc etc. Once you have that in your mind, begin to write from that perspective, for example, while keeping in the theme,
" We apologise that you will never see what we have seen, that all we have to leave you are the burnt out skeletons of old towers and irradiated fields. We apologise that the vision of silver glass against a blue sky that has kept you through this long sleep has been replaced with charred steel obscured by smoke. This was not what promised you, and we apologise.'
no that is by no means perfect, it was kind of off the top of my head, but I tried to explore the world, to give the act of waking to it some meaning. Alternatively, you could try and give a tone to the speaker that seeks absolution.
In the end, this is a good start, but it simply needs more. For a good example of this type of writing, read chasm city, by Alistair reynolds, in the explanation of why the grand civilisation of the glitter band has fallen.
I hope this helped.
ps do we have a section for writing critique, cus that would be really helpful.
