Nomads...

[Treewyrm]

Suffice to say the Nomads' tech isn't known well in general, a lot are remnants of Nomads' own experiments with human technology, prototype hybrid weapons, further adapted by third parties who scavenged those trophies. After all they were produced by infested personnel and Nomads themselves, much evidenced by Liberty's and Rheinland's utilization of the tech back at the day of SP events, but the actual knowledge and ability to re-create those devices is missing for most of the part nowadays. Some information would remain in special governmental archives of Liberty and Rheinland, but to say people know what they are actually facing... Nope. Nomads' ultimate goal or what they are still remain unknown, naturally theories exist, created by some players around and their characters, but theories they remain.
