In a barren mountain.

A blue light flashed and a figure of a young man appeared.

"So this is Keives... It's been some time since I've been here."

Serra spoke with nostalgia.

Indeed, in the past, he was escaping from a certain natural disaster.

In the Higher Planes, there are some terrifying natural disasters born in that world.

They're an absolute calamity to all who encounter them.

In desperation, Serra broke through the dimensions and jumped to this world.

He was in quite a horrible state back then.

To recover his strenght, he decided to disguise himself as a mortal and lived in peace.

He spent several hundred years like that.

When he reached his 'lifespan', he would orchestrate his death then depart to another place to disguise himself as a mortal once more.

In his journey, he met a young boy who was abandoned by his family.

That boy managed to escape alive but his family who abandoned him eventually met their demise.

After they left him, they encountered a magical beast wave and died.

Quite an ironic twist of fate.

They abandoned him to escape alive but he lived while they died.

Serra liked this boy since despite such a past, he was able to put aside his anger and focus on living on the present.

That kind of strenght... He admired it.

So he took him on as a disciple.

One day, he was able to leave.

After settling his affairs in this world, he left.

Now... How was his disciple doing?

Serra could sense the ties of karma and could see that his disciple was still alive.

"It would be boring if I just waltz in like that. So, I'll spy on him a bit first."

Indeed... That would be a boring way to greet him.

Serra wasn't usually like this in the past.

But years of boredom made him a bit more mischievous.

"First... Let's check the situation."

Serra scanned the surroundings and found magical beasts, humans and a city nearby.

"Time to head out."

Serra flew off.

Human City.

Serra appeared in a narrow street where there was no one present.

He mixed in the crowd that didn't seem to notice that he appeared from nowhere.

He looked like a simple well-mannered young man.

Serra needed information.

"Now... How do I go about it...?"

Serra began to ponder as he walked.

"Hmm... Ah yes... I remember Aura's methods..."

Serra thought about his dear wife and decided on a simple course of action.

Aura told the story of when she visited a mundane world.

The first thing she needed was information.

Therefore, she went to the best information dealer possible.

The underground information network from a powerful underground force.

Serra simply referred to them as underground since their is a myriad ways to call them.

"Now... Let's go."

Serra disappered in the crowd.

But no one noticed him go.
