The tweets in order:

1. Lady High Matron of the Red Veil coven.
First one in a new pinup series I've been working on recently!

2. Sister-vestal of the Red Veil coven and her impurity seals.

3. Sister-anabolica of the Red Veil coven, the chapter's foremost apostle to strange and distant realms.

4. Sister-venus of the Red Veil coven, jewel of the cult, first bedmate of all initiates.

5. Sister-calisthenica of the Red Veil coven, bearer of divine abs and ungodly core strength.

6. Sisters-equinae of the Red Veil coven, scouts and outriders from the Chapter of the Brazen Bulge.

7/8. Woah how did those fit in there

9. Pre-sister or sister-neophyta of the Red Veil coven, donning her assigned vestments. The last time she'll see those, and herself in this fragile form, before taking the vows of blindness.

10. Sister-palatina of the Red Veil coven. Keeper of the halls, marshal of the warriors. Clad in ancient armor of a forgotten condottiere, carries forth the sigils that speak an extinct tongue.

11. Sister-sabbatica of the Red Veil coven. Her studies of the mind complete, her third eye open, her body enhanced by sheer force of will.

12. Sister-sicaria of the Red Veil coven. At the peak of athleticism, bearing a weapon from a more civilized age, she is the hero the monastery needs. A watchful guardian. A silent protector.

13. Sister-augurica of the Red Veil coven. Day by day her intellect expands and body swells, as musky vapors of unthinkable chemicals seep surface-ward from long-forgotten vaults of those who came before.

14. Sister-abdominica of the Red Veils. Shaman of the sacred shred, preacher of the power pose.

15. Sister-hedonica of the Red Veils, who vowed to take the ordained daily penance up both her holes.

16. Sister-suspiciativa of the Red Veils. Be nice, or she'll inquisition the shit out of you.

17/18. Couple rejected sketches with different shades of Red Veil beef

19/20. Found some of the very first Red Veil sketches before they became a solid idea. And they even had a dude back then

21. One more rejected Red Veil sketch. Cut the blacksmith idea as they switched from being self-sufficient, to users of ancient museum exhibits as equipment.
