Hello everyone, I'm Gabriel.
Depending on how long I've been gone, there may be some of you who remember me as Sylar. For those of you who do, I'm sorry for all that I did to you here. I don't expect you to forgive me, I know I don't deserve it.
There's no possible way I can ever make up for what I did to all of you, but if you ever need assistance with anything, please don't hesitate to ask.
