Artav doesn't like being with others most of the time and is currently neutral, so she lives in seclusion somewhere.

I am yet to decide where she will reside, but it's probably on the coasts of the Lavanyan homeland and near Oasarian seaspace, or very close to Oasarian borders if they have territory in the continental mainland. Forget that I said that Artav's house was near the inn where most of the characters are currently at, unless it's true.

Also, her ability to create nuclear-scale destructive spells (not like she can use them anyway, but someone else or a group effort probably can) will perhaps be of use to either side, provided they are able to persuade her. I'm making her a morally flexible character of whom either side will seek after, either for getting her books or blocking their enemies' access to them. Her location is to give both the heroes and the villains equal opportunities to grab her, so first come, first serve.
