Protect Ludibrium

Do you know the source of power that makes Ludibrium run? Well, it's missing, and that's why the time has stopped. We do not know exactly what happened, and many questions are still left unanswered. One thing I'm certain is the fact that I can't do this by myself, so... I have a favor to ask you... can you help me out?

Thanks. Hmmm... the source of power can be described as the Time Sphere, located at the very bottom of the power generator, but it went missing a while ago. We've sent some people down for investigation, and the answer they gave was... well, we'll have to replace the Time Sphere.

What I'll need are 10 of the energy replacements that may in fact be able to replicate as the source of power of Time Sphere. The monsters around here have turned evil ever since obtaining that power. You will, however, be able to recover that power if you defeat the monsters.

Do you think finding it is hard? Just head downstairs, and kill the monsters that you see. It's that simple.

Did you find the item I was talking about? I want to see how it reacts...

Hmm... to see how the reaction goes, I'll need 10 energy replacements. I don't think you have all 10, though. Talk to me once you have all 10 of them with you.
