Olisa

Olisa is a little girl belonging to an intelligent species inhabiting planet X. Having gone astray in a forest, she accidentally enters the zone of aliens' secret experiment. The experiment consists of language education of local Beasts, possessing rudimentary intelligence. The study is conducted in strict secrecy. The forest is unfamiliar to Olisa and staying in it is highly risky for her. The forest is known as a hunting area of Predator, who terrorizes the locals for some time already.

Olisa can be saved, but this would break the secrecy of the studies. She can not be allowed to die however, as the investigation of her loss would lead to discovery of the mission and possible diplomatic complications. An agreed tactic of communication with Olisa, mediated by six Beasts participating in the language study, was chosen.

Unfortunately the knowledge of the Beasts is fragmented and contradictory, so the dialogue is moderated by one of the researchers, called Teacher by the Beasts. The Teacher can answer the Beasts' questions, communicate some information to them, and ask questions to gather knowledge on one's own. If Olisa can learn the necessary facts from the Beasts, she would escape from the forest and the experiment could continue. On the other hand, increasing the risk for Olisa would require a rescue operation and uncovering the mission.
