The Great Spider Goddess, sometimes called the Spider Lord (a masculine form) or the Great Spider in the Sky, is an ambiguous deity worshipped by the GIFTS and by some other giant spiders, who sometimes construct statues of her.
"She's like a spider, but really, really, really big! And she eats bugs the size of, well, uhh, really, really, really big bugs! And she's cute too." -Spider
"He's a HUGE spider! Like a god! And he makes huge spider god webs, and he catches really BIG flies, and he does stuff, and stuff! It's NEAT!" -Spider
