Ireena Kolyana is the daughter of Dr. and Mrs. Coventry, and younger sister of Dina Coventry. As an infant, she was rescued by a maid from Durst Manor before Strahd arrived to slaughter the Cult of Osybus. She was discovered and adopted as the sister of Ismark Kolyanovich, the burgomaster of the Village of Barovia. She is kindhearted, adventurous, and curious. She and her brother hired Team TRASH (pandas) to escort her out of the Village of Barovia, and further away from Castle Ravenloft, because she fears Strahd Von Zarovich. She suspects that she is of importance to him. This is likely true, as she appears to be the reincarnation of Tatyana, Strahd's first love who he is still obsessed with. However, he is currently unaware of Ireena, since the party has been actively hiding her from him.
The party found a way for Ireena to escape Barovia. She planned travel through The Shadowfell with members of the Martikov family as her guide. Once out of the Shadowfell, Irena arrived in Waterdeep alongside Ezmerelda D'avenir, roughly 3 years in the past. They were given shelter by Briall and Vajra, who hid them from the party so as not to disrupt future events.
