I know the answer to some extent will be personal choice, and to a further extent genre - romantic fantasy is less likely to have gore in it than a fantasy horror. The question still sits in my mind. I have about five fight scenes sketched out in my loose outline. The story is fairly gritty and so readers will expect a certain amount of gore, however, several of the characters are young at the start of the story (10), ageing to mid-teens as the story progresses. They are not involved in all fight scenes and I intend to dwell on the aftermath - but given that their society hold little value on the lives of the poor and uses torture and the death penalty - public flogging, the use of a mangle to elicit confessions, burning witches, and hanging, all of which draw a crowd -they will have experienced violence in one form or another. Indeed one of the reasons that the MC has for leaving his normal world is the threat of abuse and the death of a friend. What is an acceptable level of gore when participants in fights are young?
