Hisari (Location)

Ruined, half-buried city in southeastern Chult, noticable by it's golden domed roofs. Partially buried beneath a giant hill of dirt.

The group found out that this used to be a Yuan-Ti city where Ras Nsi became their leader.

The Yuan-Ti were driven out by their slaves, a mythic race of elves known as the Ultyr [spelling?]

The city was warded with a powerful anti-reptile spell that lasts until the present.
