Heart of the Mantid Swarm

All of these are in the Dread Wastes zone.

Mantid Society is at 62/48. If you take the road that goes north from Lake of Stars (SE of the zone, next to the wall) and follow it down into the "blue crack" type thing (also known as Horrid March) you'll see it in front of you. Be warned this seems be quite populated including a 90 elite. now at 60/55, which is actually a graveyard. It's west of the Lake of Stars and a little north of where the road loops (on the map).

Amber is found at the back of the The Amber vault (53/10), entrance to the chamber is at 54/16 - underneath the tree on the map to the east of The Sunset Brewgarden (in the very north of the zone), there's quite a few level 89 mobs inside, the named quest mob (Azzix'k'tai) is rather annoying as he's almost constantly casting a spell that you need to interupt.

The Empress is found in a building at 38/40. Looking at the zone map its the building a little to the east of the words Heart of Fear, just south of the tree. When you get there, there are actually 2 buildings, you want one the one up the hill. There are a few level 90 mobs on the path and guarding the building. now at now at 36/33, looking at the map, it looks like it's in the middle of the huge tree - "Heart of Fear" raid, but it's actually on the north side. Its next to a Mantid statue in a little hostile village, couple of amber topped buildings and a boat load of lvl 90 mobs are also around.

Cycle of the Mantid is at 48/34. This is in the Clutches of Shek'zeer, which is just west of Klaxxi'vess (friendly area, complete with fp). You'll have go up the small hills that are there and which are populated by 90 mobs and some level 90 elites (elites don't seem to agro). It's leaning against a lamp post type thing, with 2 domed prison cages either side.

I had quite a frustrating time with Amber - Dread Wastes.

Unless you already know this location is underground, you should first go to

/way Dread Wastes 53 15

Then follow the tunnel down into the room until you reach

/way Dread Wastes 52 10

Adding those 2 coordinates, starting at the southernmost way point & making your way to the northernmost way point will make this one annoyance free.
