Maryna and Serhiy Dyachenko

Spouses Maryna Yuryivna Dyachenko (born 23 January 1968) and Serhiy Serhiyovych Dyachenko (14 April 1945 – 5 May 2022) (Marina Yuryevna Dyachenko (Shirshova) and Sergey Sergeyevich Dyachenko) (rus. Марина и Сергей Дяченко, ukr. Марина та Сергій Дяченки) are co-authors of fantasy literature from Ukraine writing in Russian. Three of their novels have been translated into English. At the World and All-European Science Fiction Convention Eurocon 2005 in Glasgow, Marina and Serhiy Dyachenko were recognized as the best science fiction writers in Europe.

Personal life
The Dyachenkos are from Kyiv, Ukraine. For four years, they lived in Russia, then moved to California, United States in 2013.

Serhiy Dyachenko died on 5 May 2022 in the United States.

Background
Serhiy Dyachenko graduated from Kyiv Medical Institute and worked as a psychiatrist. Later, Serhiy Dyachenko working as a writer and screenwriter, together with director Anatoliy Borsyuk and cinematographer Oleksandr Frolov, was awarded the Taras Shevchenko National Prize of Ukraine in 1987 for "The Star of Vavilov" (Russian: "Звезда Вавилова") about the life of imprisoned Russian agronomist Nikolai Vavilov. The film was produced by the Kyiv Studio of Popular Science Films. Serhiy graduated from the Faculty of Scriptwriting of the All-Russian State University of Cinematography in 1989. Maryna Dyachenko graduated from the Theatre Institute of Kyiv in 1989 and worked as a professional theatre and cinema actress.

Self-description and Collaboration
The Dyachenkos describe their work as "M-realism" with the 'M' "open to interpretation." Without defining the meaning of the "M", in 2014 Sergey Dyachenko explained it as "Marina's realism", expanding "that's where the romanticism comes from, and the stubborn humanism, and the hope for white magic and a better tomorrow."

Their work have been subject to scholarly analysis.

In a 2019 profile, Julia Meitov Hersey summarized their collaboration as follows: "It is thanks to Sergey’s skills of writing solid plots that Marina’s beautiful aethereal worlds have such a strong structure, a foundation built on the characters’ flesh and bone, their blood and tears. Their ideal fantasy is a story of a real person in a chimerical world."

Novels
The Gate-Keeper (Привратник), their first novel, was published in 1994. It received the Crystal Table prize (Хрустальный стол) at the book festival Zoryany Schlyach, and the novel was awarded the title "Best Debut Work" at the EuroCon competition in 1995.

Fictional creatures and objects created by writers
This section lists unique objects and creatures, which were never used in any other works, or in very obscure works, such as "Chugaister" (Чугайстер).
 * "Glaive" (from the book Armaggedon-Home) - These are the larvae of dalphins that emerge during the apocalypse. They are deadly to all living creatures. They are extremely resilient, resistant to high temperatures, do not need shelter and are able to survive an apocalypse without taking cover. Dalphins in this novel resemble real dolphins. They have evolved to survive an apocalypse in the following way: females lay eggs once every twenty years, right before the apocalypse. Critical changes in the environment, and sometimes just the warning signs, stimulate development of the larvae. The creatures migrate back to the ocean when seismic activity is over. The next stage of their development is the cocoon. A Dalphin spends one to two months inside the cocoon before emerging as an adult. In the world of this book, mentioning of the glaives is a taboo, probably from the fear of them. The word glaive means an edged weapon that was used in the medieval times.
 * "The Yellowmore" (Желтомар) (from the book Bastard) is a wizard's trap. It looks like an old man carved out of a tree. This old man smokes a pipe that emits yellow smoke. Smoke kills living things, by homing on the body heat.
 * "The Devourer" (Зажора) (from the book Bastard) is a wizard's trap. It is a hole in the ground that attracts its victims with a children's cry for help. Approaching victim gets sucked in by a whirlwind.
 * "Calidons" (Калидоны) (from the book The Ritual) are gigantic white birds, which live near the dragons. They pluck their own soft white feathers in order to hatch their chicks.
 * "Mryga" (Мрыга) (from the book Armaggedon-Home) is an apocalypse, that comes periodically, approximately every twenty years. During this period "The gates" are formed: objects of the unknown nature, that look like a stone arch with a mirror inside. People who enter the mirror are safe from the apocalypse and are able to return after it is over. "Minor gates" are formed as well, these are used by the animals and can not be employed by humans. There are enough gates formed, so every person has an opportunity to be saved if he/she enters the nearest one. These gates are transmitting some kind of signal, but humans were not able to determine what it is.
 * "Nav", "Navka", "Nyavka" (Навь, навка, нявка) (from the book Age of the Witch) is a magic creature that takes its form after a person who has recently died. It is brought to life if someone loved that dead person and wished for him/her to come back. Nav is using deception to kill a person who brought it to life. Nav, as well as Chugaister, are taken from Ukrainian mythology, but differ from the source material in many ways. For example: in the classic Ukrainian novel The Forest Song (Лісова Пісня) by Lesya Ukrainka, the main characte is a Navka, a spirit of the forest or sprite.
 * "Chugaister" (Чугайстер) (from the book Age of the Witch, probably taken from a book "The Forest Song" by Lesya Ukrainka ) are magical creatures that are very similar to the human. Chugaisters, sometimes by themselves, sometimes in a group, destroy Navs (see above), by dancing around them. By doing so they make Navs to dance with them until they collapse dead. Chugaister was taken from the Ukrainian mythology, but is somewhat different from the original creature.
 * "Elfoush" (Эльфуш) (from the book The Well Master) is a little flying somewhat intelligent creature, which resembles an elf. Little children and people who are in love can understand what elfoushes say, thus becoming their prey.
 * "Housekeeper" (Домохранец) (from the book The Well Master) is a little house demon, looks like a little man with spider's legs.
