Ilena Otso Berg (born 2009) is the daughter of the Master Templar and Abstergo Industries operative Juhani Otso Berg.

Born with cystic fibrosis, Ilena was often hospitalized for costly treatment programs, the mounting bills eventually driving her father to retire from Finland's Utti Jaeger forces and take work as a freelance mercenary. However, this career change failed to solve the finanical difficulties, and Juhani's debt grew deeper.

Sometime in 2010, Abstergo Industries' Dr. Warren Vidic led an Abstergo strike team into the Berg home, alarming Juhani and startling Ilena from her sleep. As Juhani watched, Vidic calmed Ilena and proceeded to give her top-secret Abstergo-brand medication that he claimed would cure her ailment.

Promising financial compensation and more of the medicine for Juhani's participation in the Animi Training Program, Vidic was able to convince Berg to join him, on the condition that Juhani be allowed to kill the soldier who had awoken his daughter.
