Lee-Lun was just like any normal girl, until she got an accident while rollerskating at the age of 12. She crashed into a shop window, the glass shards mutilating her face, leaving her eyeless and heavily scarred. She needed quite a bit of time to adapt to her blind life, but it didn't stop her one bit. After all, she lost her sight, not her life!
So now she is 19 years old, and she enjoys her college life to the fullest. You can often meet her at the local bar, where she enjoys "booze" marathons with her friends.
Wait, she also a half-elf? I'll explain that another time.
I got the idea from a friend of mine, whose brother lost his eyes too. But don't pity him or he'll smack your face! 
PS: Some people told me they don't think shreds of glass could do that...and I agree. My point is that she litterally fell on the glass (so it's like her eyes were cut by a half-a-meter-long-hard glass.
