Logopolitan
The Logopolitans are a race of humanoid mathematicians from Logopolis.
Logopolitans look somewhat like Humans with grey hair and enlarged craniums, but are far more intelligent. They can easily do advanced math (such as block transfer computations) in their head and will only use computers for more mundane tasks.
Logopolitans live in the simple dwellings of Logopolis, working on various math problems. These math problems are relayed by the Monitor, and each Logopolitan works out their section of the equation just with the use of an abacus. At some point, the Logopolitans discovered that the Universe was close to reaching Heat Death. They were able to copy the Pharos Project with block transfer computations and used it to release entropy into E-Space with CVEs. They were able preserve the universe for a while, but they were constantly trying to find a more permanent solution. Unfortunately, when the Master silenced Logopolis, the constant calculations for the CVEs were stopped and entropy built up, killing all the Logopolitans. (DW: Logopolis)
