It's not bad, and I'm very grateful it's not filled with dates and history--as far as prologues go, it is nice to have a story as a prologue and not just an info dump. I'm sure it's still in very rough draft stages so I'm not gonna get at all nit-picky about the dialogue and grammar, too.
It's just somewhat hard to tell what type of war they are in. At one point she's talking about releasing huge weapons and it seems almost like the whole kingdom is on the verge of collapse--and then the next moment the Queen's Father is making jokes about when the Queen is ever going to get married, and jokes about her brother the peeping tom (who is 19 and way too old to be afraid of girls.)
Then at one point the description says they don't want another war like the one of 19 years ago but...they're in a war, right? And at the end Artis ties the Queen up pretty decisively without any appearance of the large Sentinel machine she mentioned at the beginning and he just kinda goes "No worries Daniel, she just needs some reflection time!" and it's like...very lighthearted, and I can't tell if that's what you were going for.
Also her name is Dani (Danivere) and her brother's name is Daniel? Interesting. Are they twins? I actually mixed them up because it's youknow...written down. I'm sure it won't be as confusing in the comic since they'll look very different.
Anyway, it's just a weird tone shift between a heavy war and levity, and I'm not entirely sure what angle you want to go with.
