Lovehammer Inc focuses mostly on the 31st Millennium, and the effect that the Senshi have on the Emperor and the Primarchs. Some are humorous or WAFFy vignettes of the lives of the Primarchs and Senshi between battles, others are bittersweet stories about the aftermath of the Heresy (still happens, but not as bad as in canon).
