Lamashtu or Shub Niggurath?

I'm in a Rise of the Runelords Campaign and I want to know which of these gods of monstrosity I should worship.

My character is a Neutral Evil Sorceress, enslaved and raised by an Ogre spellcaster, at a young age, as personal breeding stock because of her natural arcane talent.

The rest goes into her becoming pregnant by an unruly orc follower of the Ogre. The Ogre doesn't like this, he waits for her to become heavily pregnant, cuts it out, and cuts the head off the orc, putting the fetus and the head in a jar as an example to the rest.

In the end she's on her own, scars on her stomach like that of a cleric of Lamashtu, and hungers for the power to create a city of monstrosities in the name of her deity. She's likely to attempt to take over a lost city, because she'd rather have a city that's been built than build one herself. She's greedy, lusts after having babies with monsters, and only cares about party members when it benefits her. It's actually funny because my GM has a goblin bard that dominated a Troll.

Back to the point, which deity should I worship? Lamashtu the Mother of Monsters, or Shub Niggurath, The Black Goat of the Woods with a Thousand Young?

Given the background of monstrous pregnancy Lamashtu is the more apt.

Shub-Niggurath is more about space monstrosities and aberrations rather than warped beasts.

In rise of the runelords Lamashtu is strongly featured as the deity the opposition worships. I would very much discourage selecting her as a player deity to prevent intra party conflict and acts of betrayal.

WEll, Shub-Niggurath is also a pregnancy goddess...technically.

But I agree, Lamashtu is more apt. This is because of the difference between demon lords and the creatures of the dark tapestry- They are characterized by direct agression and ambition, while the dark tapestry is more about the long game where they wait eons for plans to come to fruition (thus they might be seen as more conservative in comparison for immediate actions... if not overall effects of their plans).

Lamashtu herself is the most notable for her ambition, since she gained the divine spark by her own hand by prying it, still beating, from a god's chest. She is also theorized in some lore to be the first demon (the result of a now very, very dead daemon horseman's experiments), and her transformation served as the paradigm used by all of the abyss, ousting its previous inhabitants, the Qlippoth (who, I might add, seem to have been the Lovecraftian horrors before Paizo just took the whole thing with the dark tapestry- some of the more alien demon lords like dagon were originally Qlippoth)

You could even make this a big point- a conflict of religion. I can easily see a cult of Shub Niggurath (which tends to be more about cells in small, rural communities) having a splinter group of the young ones that adopt Lamashtu since she represents more immediate direct action through raids and 'conversions'.

That could be a cool adventure in and of itself- adventuers come seeking to root out a cult of lamashtu, and they get help from the 'innocent' villagers who are also targets of the cult. It is only after they finish their task do they realize that the inconspicuous locals are another cult who wished to avoid attention since they have other plans waiting in the wings. An egg waiting to hatch...a seed that must be stopped before it takes root. Thus, the intrepid adventurers must abort this babe which never belonged in a world ruled by civilized gods... but even an unborn denizen of the dark tapestry might be more than can be handled by mortal means....

Anyway, for the original question- yeah, lamashtu. She is more about tearing down civilization, teaching the inhabitants of the brutal'truth' that lies just behind the veil of civility. Although... as Just a Guess said, this might conflict with the AP. So maybe see if you can alter yourself for a more Shub Niggurath feel.

Intraparty conflict is going to happen because the rogue wants to pocket everything, even the gold he sells items for. I'm getting annoyed with him for it. Yeah I'm a caster, I don't need a +2 Falchion, but it'd be nice if he offered it to the party before trying to pocket the profits.

Would it be considered a blasphemy to Lamashtu for one of her cults to destroy another in order to further their own?

I fail to see how this is a funny idea and how you'd fulfil her goal within the AP or how it's really related to a goblin dominating a troll... I wouldn't advice you to worship any of those gods (or your PC to do it for that matter either) but I would say that Lamashtu puts you on the opposite side of the rest of the party.

The Goblin Bard is part of the PC Party. He literally hangs out in the Rogue's backpack, popping out to sing or do little things that revolve around roleplay. And I find it funny because my friend, the GM, actually has The Book of Erotic Fantasy. Which details several races and who they can produce offspring with.

My character would basically worship a god that would encourage her desire to turn a lost/abandoned city into a city populated by monstrous creatures.

I'm all for an evil flavored game but what you have going on sounds like a trainwreck. It doesn't fit into Rise of the Runelords in the slightest. Good luck.

I suppose it depends on the kind of game you have (seems kinda obvious from what's been said so far...) Since Lamashtu plays a significant role in the AP, I'd advise against worshipping her if your group intends to oppose the AP's villain, rather than join forces with him/her/it. However, if the PCs are going to raze Sandpoint and pillage Varisia, then I suppose it doesn't matter who you worship. With a Lamashtu-esque character and a goblin in the group, it doesn't look good for Sandpoint. That poor town.

Well what would you guys advise for a NE scorceress that cares little for the already questionable group dubbed the "Murder Investigators" (motto: Kill them first, ask questions later). Also, despite evacuating Sandpoint, it still got razed to the ground. And most of the nobles were murdered, because they were too stupid to evacuate with the rest of the town.

Honestly it's this, or I pull out my thrallherd and just start dominating everyone into his "Tea Party". Note that the Thrallherd is actually pretty broken by 15th lvl, and mine is only built to 11th. I've done the math and can use mind control on 6 enemies with a 26 DC vs will. Which most giant-subtypes aren't good against.
