How do you get into the Helios Tower Library? I tried the elevator, but it tells me I can't use it. o_o; I looked all over the database (maps, quests, etc.) and I couldn't find it...

No, please don't tell me to do the Through the Ocean KFT quest instead. I accidentally clicked on the Through the Sky one, and I don't feel like going all the way back to Vic to forfeit it and try again... =(
