Most people suffer from too many words in their fantasy novels, but I am having the opposite issue at the moment. Currently my WIP is hovering around 50k words, with probably another 30-35k to go. That will leave it at about 85k. I am terrified that for a fantasy that will be too short.

There is other material that I can draw from, as I plan for it to be a series. I don't want to exhaust the majority of the twists in this one series. Not to mention, the next chunk of material doesn't connect well to the tone of this chunk.

Is 85k really okay for an adult fantasy? Or should in my first revision should I focus on adding an additional subplot?
