When the Emperor's Children discovered the Laer's homeworld, Primarch Fulgrim refused any notion of co-operation with the aliens, for as Imperial doctrine proclaimed, only Humanity was perfect.
In a brutal and bloody campaign fought on Laeran, the Emperor's Children ultimately wiped out the Laer species during the campaign remembered as the Cleansing of Laeran, though at high cost, for the Astartes' exposure to the Laer's corruption ultimately marked the start of the downfall of the III Legion and its primarch and their transformation into the most vile servants of the Prince of Pleasure.
