Insider's Conspiracy

I heard a terrible rumor. Someone heard that the Undead's Symbol can be found in Membreathen, and that person wants to use it.
Now, I'm okay with people doing as they please, but I can't let anyone destroy this city.

What? Evidence? I don't know if this can be evidence, but I have something. I saw them hide something in <HFFFA7272>Nocturn Yard<HFFFFFFFF> before. I know where it is, but I can't explain it to you. It was a mazy place. I will find the item while you dispatch <HFFFA7272>18 Gargoyles<HFFFFFFFF>. Your job is to keep me safe.

Don't worry. I know it's dangerous, but I'm not weak enough to be eaten by a Monster. Also, you promised me to dispatch <HFFFA7272>18 Gargoyles<HFFFFFFFF> in <HFFFA7272>Nocturn Yard<HFFFFFFFF>, didn't you? Let's do our best.

It was a talisman they hid at Nocturn Yard. I know very well what this talisman is. After all, I am a Magic Armas Comerciante. This is a Talisman of Magic Perpetuation. It maintains the magical power consistently within a certain range where it's attached. Then, can't that mean the Undead's Symbol is nearby? I can only think of it that way. Let's think about it.
