“What is the most interesting potion Afrel has brewed, and what does it do?”
Potions in the world NoH takes place in are both the highly magical fluids that cause spectacular effects (like what we would consider a potion) and much more mundane mixtures such as tinctures for staving off infection. Potions are most often medical in nature, and almost all medicines are considered part of the alchemic arts.
That being said, they can be dangerous if done wrong, so books with more powerful potions are restricted by age. Afrel, being young, can’t access too much, but is nonetheless careful about what he makes since his loved ones will invest them. So far, his most useful potion is an elixir that relieves headache and sore throats, great for when someone gets sick.
