There are other ways to make light sound evil and sinister. I would suggest that you consult a thesaurus or something but if that's the name that you really want, then alright.
Now... time for the nitpicking. First off... did you mean 'turns' when you said 'terms'? Those are two different words and it is confusing and inappropriate for describing the time duration. Change it. The same goes for 'Gallan' in your history; change it to 'Gillian'.
Second, please remove all emoticons from your application.
Third, in your appearance I assume you meant 'heels' instead of 'heals'. Again, please make the change.
Fourth... please fix your sentences to make them flow better. These particular 'sentences' for example, can be combined into one actual coherent sentence:
"It found Seth. And devoured her soul. Turning her hollow." -> "It found Seth and devoured her soul, turning her into a Hollow."
Actually, I have an even bigger problem with this sentence. You cannot turn into a Hollow by being eaten by a normal one nor do you get to take over its consciousness. This can only happen as a Gillian when a particular Hollow gains enough consciousness and will to assert itself in the mass of souls that is the Gillian. Otherwise, your spirit particles just become food for the Hollow and you technically cease to exist until purified and sent to Seireitei or Hell, mostly because normal spirits usually do not have the power to resist and overwhelm a Hollow unless they are a Fullbringer or a Quincy.
Do not fret though, for there are other ways to turn into a Hollow. Your character could have her chain yanked out forcefully or eroded over time by grief and despair, like most -if not all- Hollows.
Next... please expand on her personality. Frankly, it doesn't tell me much about her at all. Try to go into how she acts and the motivations for such acts.
And finally, please re-read your app and correct the improper word choices along with the grammar and spelling mishaps.
