Son of the Slavs

Question: Do you know of any examples of Slavic Scions? I can’t seem to find any (my copy of Dr. Hudec’s book has yet to arrive).

Thanks to our slow and backed up question log, you may have already received that book by now, but in case you haven't (or in case someone else is interested):

There is only one true-blue for-reals Scion in Slavic mythology that I know of, the first and last Scion of the entire pantheon (until, of course, the escape of the Titans and the current uncomfortable new crop of young ones). His name is Mokosits, a Scion of Mokosh, and his myth is a tale of sadness and the importance of cosmic rules.

Jealous of Perun's popularity among mortals, who worshiped him for his life-giving rains, Mokosh took on human form and seduced a mortal man named Mitran, by whom she became pregnant with a son. Seeking to avoid being caught, she went to her father Rod and convinced him to speed up her pregnancy, allowing her to give birth to Mokosits before dawn and thus hide the baby from Svarozhich. He grew to adulthood the same day, and she installed him as the first priest of the Slavs, dedicated to her alone. He made frequent blood sacrifices to her, prayed to her and told other humans about her, thus increasing her popularity and worship significantly, and in return she visited him in his dreams to reward him for his loyalty.

Stribog, however, noticed what was happening, and having already been jealous of Perun's popularity was now equally irritated about Mokosh's. He outed the Scion's existence to Svarozhich, informing him of Mokosh's rule-breaking and asking for Mokosits to be killed, both to punish her and remove her unfair advantage. Mokosh's pleas to Svarozhich and Prove went mostly unheeded, but Svarozhich decided that since Mokosits had not caused any harm, he would not be killed but instead banished to the underworld, doomed to be the keeper to the gates of Peklo and the guardian of Veles' sacred domain. Mokosh, as the first to commit this particular crime, was banned from ever again receiving blood sacrifice, and was henceforth worshiped with offerings of food and drink only.

Because of the general ban on Scions, Mokosits is the only "official" one that I know of in Slavic mythology, and things did not work out particularly well for him, unfortunately. However, gods will misbehave, so if your game needs some other historical Scions of the Bogovi, there are easy options out there. Russian folk heroes like Vasilisa the Beautiful or Ivan Tsarevitch and semi-historical Slavic heroes like Prince Marko or the bogatyrs (especially Ilya Murmotes) might be considered to have been Scions, though how long they survived, whether they were discovered and what punishments might have rained down on themselves and their parents for their existence is up to the Storyteller.
