A leisure commodity traded in Alan Lenton's interactive social MUD-Style game, "Federation". The hard-coded base price is generally 570 Imperial Groats.

Curiously, no physical description is ever given. They are required for many builds, as well as inputs in factories.

500 Tons are required to build an Energy build 800 Tons are required for a Social Security build

To build 150 tons of Univators, 90 tons of Monopoles are required (abbreviated Monos for further obfuscation).

On googling the term "Univator", I get a hit for a device described as a "Parallelogram Cultivator". It seems to be some sort of agricultural harvesting tool, but my math-geek mind wants me to think otherwise.
