Ever-Core the Punisher
Ever-Core the Punisher is a level 68 arcane guardian that can be found patrolling in three different areas in Netherstorm. He patrols in full circles around Manaforge B'Naar and Manaforge Ultris, and on the southern side of Manaforge Ara. His patrol areas are highlighted in blue on the map above.
He is very obvious when he's up because he is quite large and he looks very different from the mobs around him. He is not difficult to kill, unless your naked or something. He has only a couple of abilities and those are Arcane Explosion and Suppression. So yeah, casters might find him slightly annoying if too close, otherwise hes cake. Mmmmmm.
Ever-Core the Punisher drops one noteworthy item, and that is: Arcane Loop. It's a level 66 boe ring with a random enchant.
Chief Engineer Lorthander
Chief Engineer Lorthander is a level 69 blood elf mage that can be found patrolling around any one of the Manaforges in Netherstorm except for Manaforge Ultris. His patrol areas are highlighted in red on the above map.
He is not incredibly obvious when he is up. The only really distinguishing thing about him is his weapon. He wields a weapon that is completely unique, specifically a keyblade. You may recognize his weapon from Uldaman, where you needed to attach the shaft of Tsol and the Gni'Kiv Medallion to create the Staff of Prehistoria which opened the room to Ironya.
Chief Engineer drops one noteworthy item, and that is: Illidari Cloak, which is a level 66 boe cloak with a random enchant.
Nuramoc is a sweet level 70 unique Beast Mastery chimaera pet that is unfortunately needed for the Bloody Rare achievement. His patrol areas are marked in green on the above map. He's so flippin' cool that he has an entire post dedicated to him right here.
