Hi there firstly love the work, super cool especially the Death Idol ones (Necromancer Hatsune Miku rules ngl) but as i was browsing the book i came across page 43 under the paragraph Claim your Tomb which states and i quote "All Necromancers select 1 house of choice from either Core, TSBH, or this book." the part i do not understand is the TSBH part. i do not know what that is as i have searched in both the Core book and the current one and this cool book here too and i dont know these factions; same for page 48 with the Apostexx, R.O.T Corps, Pruzcz, Black Carpet, Lily Stone and Permia. i have never seen those factions till now. is there another book i do not know about? i do apologise i am rather new at this.

Thank you for your help, much appreciated.
