This is Gwydion. In myth he’s often referred to as a “trickster”, which is a bit of a lighthearted nickname considering his actions (deliberately started a war as a part of a conspiracy to commit rape, and ends up killing Pryderi in the process). While he is punished for his crimes, it still seems like he’s written as one of the good guys in the end which I always found odd. He also helped with the creation of Blodeuwedd.
So my character is like that in that he appears to be a hero and of good moral standing publicly, but is secretly an awful person who will commit crimes if he knows he’ll get away with it. I can contrast him with a fairy character I’m thinking of who cannot break the law because they physically can’t, and is worried that they would be a bad person if it weren’t for that.
I had trouble deciding what he should look like. I’ve always imagined him as quite young for some reason. He must be aged somewhat since he is an accomplished magician and bard. A 2003 film depicted him as being an older man, while I’ve always imagined him as being a young and arrogant type like Calliou from Recettear (though maybe not that young). Then I thought maybe he’s a bit like Zant from Zelda.
Another minor thing about the design is that the jewel in his staff is visible whatever side you view it from. i.e. it is never obscured by the ring that surrounds it. You always see a full circle with the ring around it. Even if more than one person is viewing it from different angles at the same time.
One thing that has stayed constant in my mind about his design, is that he has dark hair in a bowl cut. I don’t know why, there’s just something about the name Gwydion that says “young with a bowl cut” to me. I’ve never met anyone called Gwydion irl, but there was someone my brother knew from school named that, and I always imagined him that way too.
Also a fun fact, an old Welsh word for the Milky Way galaxy is “Caer Gwydion” which means fort of Gwydion. However I much prefer the modern word “Llwybr Llaethog” which is a literal translation of Milky Way, because it alliterates and so is fun to say.
