I'm looking to make a Slaves of Darkness spearhead feel more Slaanesh-like. Are there any good 3rd party companies or STLs that I can use to add some generic Slaanesh banners, icons, symbols or any bits that aren't demon tentacles and claws? I'd rather not buy a new box of minis just to get one bit, too. I've had a look around and all I can see are bits for space marines. Thanks for any help.
