@Beeslayer I think this post might have needed its own thead-line. I believe what you have is an Epipremnum commonly referred to as 'pothos' or house ivy. It doesn't look what I've seen called 'Creeping Fig'.
If I'm correct, it does appear to be in bad shape. It might be that the stems near the soil level have life and will put out new growth. Mine does look similar to that after it comes inside during the winter months. I generally shear mine off and wait for new growth which has always come back in abundance. In case those roots are too impaired, then if it were mine I'd find green sections of the vine stems and try to root them - either in damp potting mix or in water. In my experience they will root fairly easily either way. I live in an area of low humidity, though probably not as low as the high desert, and it thrives. It also makes a great container plant for inside. I'm just a terrible caretaker for inside plants and have too many so it suffers in the winter months.
Here's a photo of mine from several years ago, but this s how it looks currently.
