I've been trying to get to the quest marker for Chapter 2's Death Symbolized quest in The Witcher 2. Every time I start walking in the direction where its leading me I end up back on the wraith invested battlefield; which is an entirely different map. I tried backtracking to the spot where the guards won't let me pass all the way into Vergen. From there I only see a path that takes me down into a harpy-ridden ravine which offers pretty much a dead end.
I've tried going through Vergen but the city is totally blocked off at both entrances. I must be missing a passage way or something before the city gates. Where exactly am I supposed to go for this quest?
