I´m not sure if it´s possible, but here some topics I would search on in this module:
- Connections with Ulor and also (!!!!) Ly-Aran
- Border traffic to and from Saralis
- Trade links with the rest of the world
- local gods and/or spirits
Basically I always had problems with the "stand-alone" decreptions of Ulor, Ly-Aran and Xa-ar. (" Xa-Ar was the second large country that fell to the powers of the white lord early during the second era. Since then not much is known about the country..." or "A land not much known about, Ly-Aran was a peaceful land that fell under the power of the white lord in 3750 S.E.I. [...], and not much has been heard from the original population since then."
So in my mind there are more the questions of linking this stand-alone solution Xa-ar more to the overall picture. For example what´s about all this ship trade entering the bay of Ulor heading for example towards Cynar.
What are the goods coming out of Xa-ar? Something special? Probably, even if there is some kind of bane, there are smuggling activities.
And hopefully there are some links to the pretty good stuff of Jonas Cedher. Who did a lot of impresive work about Saralis!
