Preparation

I collected some information about the monsters that used to haunt this place, and compared them with the crystal sample. Our situation does not look good.
During previous Eye of Wisdom raids, there was one monster that was able to resist and fisgh back against our magic. This monster was called Pirlanok. Ultimately we had to rely upon the hero Logar to defeat him.
However, no one saw that battle, and we received no further information on Logar or Pirlanok. We only know that the battle took place within the Dead Tree Cave, and I... I believe that fact that this magic force is in the very same cave cannot be a coincidence.
If we will have to deal with Pirlanok, relying solely on my magic will not be enough... But if some of the magical items used in the previous monster raids have been left behind, maybe we can use them...
Ahh, I have an idea! Logar's Agnes is very familiar with this topic, perhaps she will know of any items that might still be left!
Can you go see her? I must begin preparing some things immediately.

The talisman for defeating the demon...ah, what was his name...Larpinook? Pizzletook? Oh, right...Pirlanok.
Yes, I remember it now. Those were dark days indeed.
In order to deal with Pirlanok, the mages of the Eye of Wisdom made a special magic item, but it was no talisman. No, it was a weapon.
Let me regale you with this tale of power and weakness, of victory and woe!
