This zone is just a single room. The floor patterns are elaborate. I left some of the complexity out, but this map is still pretty busy. I'm thinking this is a reasonable representation.
The zone entry is in Zimara Breadth.
Code:
<ImageStyle Name="exp20_dun_prelude_raid_01" displayname="Vaashkaani, Alcazar of Zimara: Chromatic Chamber [Raid]" zonerect="-404, -431, -203, -280">
<ImageFrame Source="images/maps/map_exp20_dun_prelude_raid_01.dds" SourceRect="0,0,800,600" />
</ImageStyle>
