Lyhde is a Viera (character with rabbit ears) with green hair and yellow at the tips and is fair skinned with a light green sheen to their lips.

Caolan is a young boy with a red cross painted on his face, one of his eyes is clear/white and barred by a scar, the other eye is brown and hidden behind his fringe. His hair are a dark red with some light green strands.

There's also some like #Lyhde who's identity is so outside of anything known that the way they live goes beyond expectation and rules to the point of queerness would even start to explain who or /what/ they are. #Caolan is also in the same case with #Meabd, two entities in one body.

Before they were stuck in Veira's skin, #Lyhde was a pixie on the First who befriend the real host of the body through their dreams.
They're nature as pixie make them mischievous but to live as a "somehow" mortal body (even if it takes its time) gave them another perspective & fondness.

I really love the fact that #Lyhde is not what they seems. They're older, far more than regular Viera ; they could use what is the most powerful magics but don't, unless it's to fight void mages (not voidsent) ; they use powerful glamours to hide many, many things about them but not only.

#Lyhde is the result of void experiments by Mhachi who was rescued by Amdapori and helped them during the War of Magi if only to get revenge. Therefore, Lyhde is a real black & white magic caster.
They lived through many calamities and just live on the side of everything, waiting to return home.

#Ceylan ears will immediately move away and he will definitely be very defensive or even respond violently since he had to deal with people grabbing it and use it to control him in his childhood.

#Lyhde is fine with people being curious and touching it as long as it's not done harshly or to harm.

#Lyhde will be all fun and affection but it's a tragic romance as they know they will outlive you (but they will keep you living in their memory).
#Ceylan is this really hard character to romance, little pay off and honestly, if it wasn't so fun to see them flustered, there will be no point in it.
