Вы используете экран с опцией #NETHACK.
Nethack - это старая текстовая игра со множеством неожиданных поворотов, в том числе зависимостью от фазы луны. Если это полная луна, то в игре сильные монстры.
Экран имеет возможность переводить некоторые обычные сообщения в сообщения 'nethack-ish'.
Одно из сообщений Nethack: «Будь осторожен, новолуние сегодня». Экранная версия этого «Будьте осторожны! Новый экран сегодня вечером. ")
