The Nyx is a light BattleMech originally developed by the Word of Blake in the late Jihad. The Blakists' designs for the 'Mech and a prototype were captured by the Allied Coalition's Draconis Combine force on Quentin in 3077,[4] and were rushed off to the Draconis Combine's Diplan MechYards, where engineers did not have the resources to put the advanced design into production. After the liberation of Terra in 3079, the Combine would ask aide from the new Terran government to assist with development of the 'Mech. It would be jointly produced by both the Republic and Combine, prior to the very end of the Jihad.[5]

The design was conceived as a speedy recon 'Mech, with a Pitban 300 XL engine allowing it to reach 162 km/h. The design utilizes a Beagle active probe as part of its role as a scout 'Mech. Its hull is protected by five tons of ferro-fibrous armor, so it can endure enemy fire long enough to fulfill its mission.[5]

Weapons and Equipment[edit]

The Nyx has a pair of arm mounted Diverse Optics ER medium lasers to provide it with moderate long ranged firepower. When the 'Mech closes in, it can bring its SRM-6 and Diverse Optics ER small laser to bear. The waste heat from the weapons and other equipment is managed by 10 double heat sinks.[5]


WizKids MechWarrior Dark Age Variants[edit]

  • NX-23L 
    This is a post-Jihad variant of the Nyx which trades its medium lasers for a pair of blades, offering a close combat option not dissimilar to the NX-90. It was favored by Katana Tormark when deployed with her Amaterasu regiment.[14][15] (As of this time, there is no Record Sheet available for this variant.)
