So one of my players got implanted with some Huge Monstrous Spider eggs the other night. I gave her a couple of Fort saves to see if her body would reject the eggs but, luck of luck, she failed. So can anyone think of any plausible ways that she could somehow bring some sort of hideous spider/human baby to term? I'm thinking it'd look pretty similar to a drider (except with a human half rather than a drow), be less powerful, be a baby, and maybe have some nice mandibles protruding from its mouth. But I just can't think of any believeable ways for a human to conceive such a hybrid. Any suggestions?
