Infiltrate

Wow, you're back and you got the Lambent Essence? That's crazy! What about the Dragon Warrants?

Great! These aren't for the spell, I just wanted them. Keeping them in my pocket makes me feel brave! Well, more brave. A little.

Anyway, here's the real mission!

If you can defeat all the corrupted guards in the Temple of Darkness Corridor, you should be able to use the Lambent Essence to break Arkarium's warding spells.

Don't try to use the Lambent Essence before the guards are gone, but it should work just like any other item once the coast is clear!

Aww, are you mad about the Dragon Warrants? I really DID need them. I promise!

Did you break the barriers that were blocking the Dimensional Schism?

Wow, I could never have pulled that off! Some of my sneaking skills must have rubbed off on you.

Do you think you can get into the Dimensional Schism and defeat all the corrupted guards? You'll have to use that Lambent Essence as soon as you can so the other guards in the area don't detect your presence!
