So, I know the Death Korps use cloning, and that there are genetor Tech-Savants trying to recreate Space Marine geneseeds, and that the Inquisition likes to do all sorts of experiments to try and create their own supersoldiers, but are there any other reasonable reasons for someone in the Imperium (specifically on a Forge World) to be screwing about with gene-tech and test-tube babies? Are there any cases of Tech-Priests maybe trying to use gene-tech to improve their Skitarii? And do Skitarii ever get to retire, or get forcibly retired or abandoned or just disbanded in the middle of nowhere like Imperial Guard regiments often do?
