Necro Fissure armour.

So I've been wondering..
I only see Elementalists and warriors with fissure armour (Either that or I'm too dumb to distinguish)
But I never see necros with it. (I can't tell apart the other professions' armours, so I'm not sure about them)
I tried getting a set of fissure armour myself... But upon making it to the forge, the forgemaster beset me with quests, which my group couldn't really finish because half of them had to leave.
And this has left me with a few questions...

1. what does necro fissure armour look like? (Pics pl0x!)
2. What do I have to do to get the forgemaster to craft it for me?
3. Will I have to re-do any of the quests, etc. to get him to craft it for me if I return after doing them already?
4. What materials do I need?

Any help would be appreciated, thanks.
Sorry if this is in the wrong forum, it just looked the most fitting for my questions.

2. There is a quest where you defend the temple of war against hordes of shadow warriors. After you do this talk to him again and he will have a menu of the armor he can craft.

3. Pretty sure you don't have to do the quest over and over.

4. Depends on your profession but the main ones are ectoplasm and obsidian shards. (about 3-4k each if you buy them)

I did the quest where you have to defend the temple against the 11 teams, all that came up was the option for 2 quests...
