I got tired of getting lost in this zone, so here's a spiffy new map for it.
Code:
<ImageStyle Name="exp07_dun_crystalcavern" displayname="Crystalline Breaks" menugroup="Velious" zonerect="-224, -161, 119, 237" >
<ImageFrame Source="images/maps/map_exp07_dun_crystalcavern.dds" SourceRect="0,0,436,506" />
</ImageStyle>
