OK I'm like 80% settled on painting my Sisters as Our Martyred Lady.
It seems a bit unnecessary to do my own Order when the existing Orders already have so much space for /yourgals/ plus I'll have access to the icons and transfers
In terms of lore I like Bloody Rose a bit better, but I do prefer the more nuncore aesthetic of OML. I may regret this if they ever do a model of BR's main Saint, which is like a cross between the Emperor's Champion and a Berzerker. That character sounds extremely cool. But I know to never make decisions based on what models GW might do at some point in the future

So I'm thinking that OML is the ticket
