Besmara is a Deity of Pirates. Raiders on the Sea. Her Edicts are to take what you want, no matter from whome or what reason. The only redeeming quality in her edicts seem to stay loyal to your crew. Your fellow crew of murderers and thieves, so you can successfully raid ships.
She herself became a deity for two reasons:
1. because she terrified sailors that she would send monsters after them (and probably did).
2. she killed multiple Spirits to ascend to Deity Status.
The one mention of non-pirates worshipping her, straight up ignore the pirate part of her worship. Which seems more like appeasing her then actually worshipping her. Or at the very least, Apocryphal?
Like she demandes almost the same things as Norgorber, the God of Murders and Thieves. Yes there is a loyalty demanded towards your fellow Pirates, your Partners in Crime. And there is no need to hide your identity. But like the point that makes Norgorber evil, is still shared. To do what you want, at the cost of others.
So.....how is there any form of being Holy? Any hint that there is a Well intended Follower of this Entity?
Lets take Calistria for a counter example. She is selfish. and wants Vengeance, but she doesn't demand that you just don't care for anyone else. Just that you get what you want and respect Vengeance. It is never specified that you have to take from others, ruin their properties and lifes. That is for me someone in the middle, you can lay out her teachings to be a killer who just takes what you want, but it is not specificly asked to be vile or merciless to follow her.
While Besmara you have to take what you want. its literally her Edict.
So what am I missing?
I don’t really have much commentary to give on this, but I checked the Divine Mysteries Web Supplement and her sanctification says “can choose unholy” so it’s either no sanctification or unholy sanctification; there’s no option for holy sanctification with her.
She does allow heal, but I assume that’s just part of being able to maintain crew health. Nor do I think that indicates holiness when Lamashtu apparently also allows harm or heal as a divine font. Dunno if that answers your question though.
