Tamuero was a city on the planet Brakur IV that contained an outpost of the Scythes of the Emperor Chapter.[1]
This outpost was used following the loss of the Chapter's homeworld to the tyranids of Hive Fleet Kraken, in order to conduct genetic screens of Brakur IV's populace. It was hoped that the native population would be suitable to recruit new aspirants for the Chapter, which had been devastated in a series of battles against the tyranids. However, the outpost was abandoned when the tyranids invaded Brakur IV as well.[1]
