It is a deep forest spanning the borders of Illustria, Manastella and Morfan. A woodland that is compatible with, or more demanding than, the Silva forest.

There was a man standing outside the woods.

"This is the Lost Forest"?

"If the store people ask you where it is, this is the right place, right?"

I went to Elgin's material store to wholesale herbs - they asked me to bring them if they were still there because they were of good quality - and when I went, I talked about the "Lost Forest" in a chat with the store's grandfather. There seems to be a variety of rare materials in that forest where high elves live in hiding, but the story is that those who get in get lost three days and three nights on the road or in some cases lose their lives. I was intrigued. I heard the location from the store's grandfather. My grandfather told me not to come in scattered, but at the end of the day he broke and told me.

I heard it was a place spanning the borders of Illustria, Manastella and Morfan, and once I moved to the Morrow dungeon, I flew up in the sky...

"Yes, what is it?

'No, this is a dungeon, isn't it?

'Huh?'

"No?

At first glance I masquerade, but I also know to some extent the internal structure whether I am the fault of the Dungeon Master.

'... oh, it's cleverly hidden, but there's a transfer trap everywhere... the lower tier is built the same... the trap itself is huge and the surrounding vegetation is engineered to look the same... now you won't even notice it was skipped... it's just an illusion with the wide woods... well, there are no monsters and few traps up to ten layers. It's just... there's some magic hanging in there that inhibits the sense of direction. Besides, it's powerful enough to go to the lower tier... a little trap comes out of the eleventh tier... oh, the sensory inhibition of the twentieth tier is cruel. Now I don't even know if I've turned right or left in the direction I came. Hmm... the monster has come out too... Arlaune in Trent, is it a classic around here... in Sleeping Flowers, Pitfall Nepentes? Oh, you use a capture bag disguised as a pit on the ground to capture prey...'

"Um... Master, do you even know that?

"Oh, I don't know why, but the structure itself is slipping through, so you can see the whole thing.... I think this is a problem... '

There are other odd points.

'Something, this dungeon, the update... you say it hasn't been taken care of, or it seems it hasn't been modified or improved in a long time...'

But you're well thought out as a dungeon, this.

"Yes, Elf. Huh?

'Hmm? Oh, I didn't tell you. There's a cleverly hidden gate, maybe beyond that... there's a village. Unlike a trap, it's a mechanism that no one can get through except the certified ones.'

"It's an abandoned elf village..."

"Keane, it's not an" obsolete "elf, it's a" high "elf. Don't get me wrong, okay?

'Oh, yes. So, Master, what's a village...'

"Wait a minute.... I have a dungeon core-like reaction... what? Oddly enough, the signs are faint... ahhhhhhh, I see... '

"Yes?

"Master?"

'Oh, I'm sorry. It's a dungeon core here, but apparently, it's called Kamiki? You're taken in by it... or you're fused. Is it because of this that the signs are rare? And then, on top of being captured by Kamiki and not being able to wield his full power as a core, an update of the Lost Forest because he's via the gate...... he's not able to take care of it'

'Really?

'Oh, the dungeons here are double structured. It is in the village of High Elves that Dungeon Core has direct jurisdiction... the village itself has become a kind of dungeon. Outside it's a structure of a lost forest unfolding across the gate.'

"Yako no..."

"Why are you building that? Master."

'No... even if I asked... maybe, but at first it was a single dungeon, wasn't it? Perhaps it was a mistake to install the gate that separated the lost forest from the direct jurisdiction of the dungeon core. "

When I talked to him about it, someone called me to my heart.

"Wait... communications came in from the dungeon core..."

"Is that right here?

"Oh, you're from the Dungeon Core of the Lost Forest"

'What are you saying? Master?'

'Wait a minute...... oh, sounds like it was the elf dungeon master who made the dungeon here. A long time ago... I heard he was in old age more than a thousand years ago. Oh...... was that also the reason it wasn't updated...... what?

"Master?"

"Yes?

'... I've been asking you to help me strengthen the lost forest. Because I'm sending the use...'

"It's sudden."

"Yes, that one."

Looking in the direction indicated by Rye, there he was...

"Master Spirit?
