He woke up in a stone room illuminated only by the faint light coming off a white orb on a pedestal in the middle of the room. He tried to look around before realizing he could see the whole room at once.

Huh, I don't remember having 360° vision, he thought as he started to move towards the only exit before realizing he couldn't move.

"So first I have to choose an element"

His gut pointed him to go for the strongest choice.

"Fire seems strong, " He thought as he chose fire.

"Hmmm, I wonder if that's any good, though definitely choosing Elementals"

"Demons sound like a bad idea with the whole divine quest thing going on"

"So Constructs and Lizardmen"

After the monsters were chosen an orb of light appeared suddenly and when it receded a small blonde girl about 6 inches tall was in its place.

"Hello Firstborn"

"Huh"

"My name is Kara, and I am your dungeon pixie"

"Hold on, Why did you call me firstborn"

"Your title is firstborn silly let me show you"

(Titles)

-Firstborn

You were the first dungeon.

+1 starting monster choice

"Ohhh, so that's why I got three choices, did the other three get the same reward?"

"Nope they each got different rewards depending on their birth order"

"That makes sense I guess, though call me John"

"Ok John" Kara twirled in the air before stating, "Let's start with the basics, try saying dungeon store"

"Dungeon store?"

[Dungeon Store]

"Good job," said Kara clapping

"Now let's try bringing up the dungeon map"

He waited for a second then said, "Dungeon map"

The map showed a single room with the entrance labeled.

He looked at the map before asking, "how do I make more rooms"

"I was getting to that, now it's simple just will your mana to break down the wall"

"Mana?" He questioned

"Mana is that force inside you"

As soon as Kara pointed this out he realized he could feel that force and willed it to carve out a door opposite to the present door.

"Whoa, " he muttered surprised to seen stone disappear

"As a dungeon mana naturally follows your will, try summoning a lizard man"

When he tried to bring a lizardman into existence he realized he could see in his mind what they looked like and the different types there were but the only one accessible was the basic Lizardman.

As he willed it so a 5 foot tall, scale-covered humanoid with the head of a lizard appeared in front of him.

"This is fun"

Kara laughed before getting serious, "you must expand your dungeon and defend your core"

Surprised by the sudden change in the tone he asked, "Why"

Kara responded by saying, "If the core is broken or taken from your dungeon you will die. The inhabitants of this world have been told by the gods about the dungeons and they told them that by taking your core they will get a major power-up"

"Whoa"

Kara continued, "But don't worry all the peoples of this world are tier one for now but they will start to grow and advance now that you and your fellow cores are starting to purify mana"

He was silent before saying, "Well then we should get started"

Kara smiled before saying, "We have a 30 day grace period before anyone can enter"

He looked relieved and said, "Well that gives us some breathing room"

He then excitedly got to work carving the first floor of his dungeon.

He started by carving a long hallway from the door he made earlier. At the end of that hallway, he made a massive circular room where he planned to put a small village of Lizardmen.

"Is there an easy way to put an environment in here or do I have to plan the whole thing out from scratch," He asked hopefully

"For the first floor you can buy a basic ecosystem but for later floors, you will have to do it by hand"

"Oh ok"

He opened the dungeon store

[Dungeon Store]

(Floors)

(Monsters)

(Traps)

(Flora/Fauna)

(Environment)

(Other)

He tried the environment tab but he couldn't find it.

"Is there an easy way to find stuff in the store," he asked confused

"Just focus on what you want and will the menu to it as you did with mana," said Kara cheerfully

"Oh," he said feeling stupid for not thinking of it himself.

He did just that and found it.

(Flora/Fauna)

-Basic ecosystem

Basic functioning 1st-floor ecosystem

Cost- 200 DP

He bought it and watched as the whole first floor transformed.

The stone turned to dirt as grass and trees sprouted from the floor.

After that, he summoned more Lizardmen, 4 more males and 5 females. The females look identical to the males except for slightly wider hips.

"Start to build a village and mate, " he commanded

"As you wish creator, " said the first Lizard Man created

After that, he put a hallway coming off the circular room mirror to the first hallway.

"Let's put some traps in this hallway"

He looked through the trap menu for some basic traps.

(Traps)

-Pitfall

Pit of wooden spikes covered by basic camouflage.

Cost- 50 DP

-Dart Shooter

Small launchers that shoot darts when foreign mana signatures walk by.

Cost- 100 DP

-Falling Logs

Logs that fall onto intruders when they step on the pressure plates

Cost- 100 DP

After buying the traps he filled the hallway with various traps and put a few in the earlier hallway.

"Ugg" He suddenly felt weak and couldn't tap into his mana.

"What's happening"

Kara floated over and explained, "When you use all your mana you will become weak"

"How do I get more mana," he questioned

Kara tilted her head and said, "Every day you will get 1000 mana per floor up to floor 5, and you get more dungeon points when you kill intruders or if you have a certain amount of intruders in your dungeon at a given time"

"Ok so I want to have intruders in my dungeon but I don't want them to get to close to my core"

"Exactly," cheered Kara

"I guess I just have to wait till tomorrow"

Kara smiled saying, "Go go sleep I will wake you up when you have more mana or if something major happens"

"Thanks, Kara you're the best"

"I know"

With that, he closed his figurative eyes or really just moved his vision from the dungeon completely and slept for the first time in this new world.
