Phoenix And Zhar-Ptitsa

A really random idea I've got all of a sudden... A phoenix and a firebird (slavic zhar-ptitsa), meeting somewhere at the World Tree, and both feeling quite an attraction toward each other (yes, the phoenix is clearly male here, and the firebird is female). In the Russian language, the word "feniks" ("phoenix") also has a male grammatical gender, while "zhar-ptitsa" ("firebird") has a female one. The phoenix's design is more or less based on an eagle, while the firebird's clearly on a peacock (yes, I know the difference between peacock and peahen, but it seems firebirds of any gender have a resemblence to a male peacock). Anyway... The phoenix's offering an Apple of Youth, because firebirds liked them.
