Whilst I do not wish to belittle what the OP may have felt where does one draw the line? What triggers one person does not someone else. What about people that have deep phobias of such things as spiders or lots of small holes? I hope you see what I am trying to get at - you simply cannot cover everything. The player themselves needs to take responsibility and admit that this is a fantasy game in which bad things can and do happen.

If there are severe effects from seeing such things then with the deepest of sympathy I would suggest you simply avoid this genre of game.
