==Description==
You look at the book, not knowing how to open. All your attempts have met with failure. You are about to give up when a voice enters your head, it is vaguely familiar.
"Et ignis a aperietur vobis."
You shake your head and look around, you see only Tylious staring at you. The voice repeats.
"Ignis."
You again look around confused, you approach Tylious and ask him.
"Ignis? Sound very similar to ignite. Why do you ask?"
You shake your head and wave off your comment. You have an idea in your head, you just hope there will be a fire soon.
==Objectives==
*Survive 5 Bloodflame attacks by Cruentus
*Defeat Cruentus
==Completion==
The book flips open as the body of Cruentus falls to the ground. You flip through the pages only to see that you can't read the language it's written in. You approach Tylious with the book.
"I said I don't care about your book <name>."
Tylious looks down at the book quickly.
"But I can tell you there is only one who can decode that for you."
