Mostly human with drow ancestry, actually. IIRC from when Runey posted the concept ages ago, she had a neuromuscular issue from the drow ancestry and could walk for brief periods, but usually used the wheelchair to get around.
If this is the next character Runey adds which i remember seeing concept art for,
Would work out good for me helping me getting my flatmate hooked.
I've been getting my flatmate into this game slowly but he does not have a character he feels he relates to.
(Thought he might relate to autum as hes a sexually repressed pastor but nope

)
he is however a partial parapallegic in a wheel chair who can walk for short distances, So wheelie does sound promising as his relateable character depending on how Runey does it.
He likes the game which is a surprise as he's hated almost all other VN's I've introduced him to.
He says Ashley reminds him of me, I'm inclined to agree especially her birthday scene.
(We had a similiuar experience after moved into this house and had my first birthday here, First time i felt like I had family that cared. They may not be blood relatives but I now have 2 brothers that are closer to me then any blood relative i have. I still keep my knives handy though, Its more to protect them then myself now though.)
