So the Tithe Legion it´s going to be a completly new legion of Nagash?? Or just another OSB legion like Petrifex??
And about SoulB and LoN... maybe we can get both Battletomes. SoulB for a vampire theme force and LoN with zombies, skellies, etc... that allow you to mix the themed bts (NH, OBR, SoulB) with the core LoN models, allowing you to mix some units depends of your legion (If you use Sacrament, death with OBR; same as Grief now).
