Curse of InniStrahd
Ismark the Lesser
Ismark is the biological son of the late burgomeister. He is less dour than the regular Stensian and is eager to greet the PCs. He even buys their drinks for them. However, he is chiefly concerned at the moment with his adopted sister, Ireena. He wants to move her to Lammas, where he feels like she will be safer from Strahd. He implores the PCs to help him convince her to go and to protect her along the way.
He then takes the PCs to the mansion and introduces them to his sister.
