So been kicking around the idea of a unifying theme for my Imperial Armies (to try and get me to paint them!!). Re-reading the Badab Wars books and there it was!

The Tyrants Legion. Based around a core of Astral Claw Marines but can use my hordes of guard amongst the other stuff I have planned. Will be offloading the Tau and Eldar stuff that I have to make room for it but figure it will include:

4k of Marines
4k of Krieg
6k of Ulani (love my tanks...)
3k of Knights
3k of AMTL

Already have the bulk of this and selling the other bits should fund the titans.........
