Fissure armour and regular 15k armour

Are they the same thing of different? I know they have the same stats as forge armour but do they look different? And are there any places where i can get pictures for both?

check the screenshot forum, plenty of pictures of both have been posted. As for your other questions. Fissure/Obsidian Armor has the same stats as Droknars and Ascension armor, however it looks different (more menacing if you ask me). Furthermore, while there will be all the different types of Obsidian armor (knights, gladiators, etc) they all look identicle to each other, just different stats.
