When a person remains in the Gray Waste for too long all their colors get drained away and so do their hopes and dreams. They end up having no desire to leave the plane. There are plenty of ways they may end up leaving not of their own volition though. For example, a loved one could find them and drag them back home and since they don’t care about anything I don’t see them resisting, or they could get kidnapped by a fiend, or they may just have wandered off onto a rocky outcropping and failed a Dex check so they ended up falling into a portal to another plane.
My question is, If somebody ends up outside of the Gray Wastes after they have already passed the point where they’ve lost everything but have yet to become a larva or shade will they return to normal?
Will their colors return? Will their hopes and dreams return? If so how long does it take?
