Started reading the Ahriman Omnibus. Thousand Sons have always seemed cool since I read about the Rubric marines back in 3.5 and the novel and stuff in the old codex I found are cool too. Anyone have any experience with them on the tabletop? Watched a few batreps where they seem cool, but I dislike how it feels like everyone brings Magnus. I was fluffing out a custom warband but I am not sure if it is too Mary Sue or opposing the lore.

The leader of the warband is a renegade marine not of the Thousand Sons, trained by a Thousand Sons sorcerer. He has a small force of Rubrics and some Tzaangors, but they function as mercenaries that trade their services in war for knowledge and secrets. From what I understood anyone with knowledge can order around the Rubrics, but I might be wrong? Felt like a fun idea to have a TSons sorcerer who has his student/Cats Paw doing the dirty work and fighting for him and the mentor only showing up in times of dire need. The renegade would wear the colors of my CSM warband and be the new CSM sorcerer with some TSons bits/conversions. This would let me run him with my CSM normally and also run him and his thrall Rubrics in the CSM army if I feel like it.
