Caring, passionate, intense, competitive.
Eliza always had dreams of pursuing a career in the tack-making industry, but unfortunately this didn't get her anywhere; she wasn't able to gain a foothold and ended up being overlooked for other, more "popular" designers. So instead, she decided to move in with her friend Lazarus on his farm and assist him there. While farm life really isn't for her (she rather detests it, in fact) the fact that she's helping her friend pushes her to continue through it despite her reservations.
As for riding Stryx, Eliza is...untrained, to say the least. While not afraid of heights like her friend, Eliza finds riding uncomfortable and doesn't understand how to command a Stryx. Still, she tries...and with Lazarus helping, she'll surely accomplish it some day.
