Face Lolth in her lair.
We have found the Spider Queen’s lair in a cavern deep beneath the city, guarded by zealots and thralls. Solistre warns that the true danger lies not in Lolth’s guards, but the goddess’ deceit and trickery.
A little ‘what-if’ scenario I’m playing with for Sol’s ‘personal quest’. Lolth issues Sol an ultimatum: submit to Lolth’s service and be blessed as her favoured assassin again, or die and have her soul claimed in the Demonweb Pits anyway.
Lolth wears Sol’s face from another realm of possibility - one where she had fallen back into Lolth’s embrace. She takes on the form that Sol would hate to become, taunts her with it, dangles the promise of power laced with the poison of eternal subservience.
She knows Sol hates it - and she revels in the fact. This is why Lolth kept her in service for those few years, then went silent to Sol after releasing her; keeping her in a state of religious limbo and feeding on her visceral hate and fear, her habitual worship despite her own uncertainty under the goddess’ dominion.
Lolth loves making toys of her children, and this one provides a certain flavour of amusement she enjoys. And if Sol wants to break away…well. Only if she is not broken first.
