I'm interested in seeing where this goes. I really liked your french couplets, so I tried to make english versions of them:
Maelbjorn
An heir, heaven sentenced to perdition
The sword has become his chief ambition
Akhet
Peckish fear and exile keep him wary
The southern minstrel seeks sanctuary
Vekad
So strong and slender, the lord of the hunt
Pursued by phantoms that he must confront
Tenoch
Heir of the dragons, lover of the flame
Avoiding cold and blade should be his aim
