The hole rapidly expanded until the trio could see the other side, which was a white room with a platform. Around this time, the Holy Silver Divine Door began its counterattack to destroy the nanobots.

However, it was far too late, with an opening present, Darius teleported his group through the hole. Technically, he could have used Group Teleportation from the very beginning, even if the door had remained closed, but that would have been utterly foolish.

After all, how could it have been possible for him to be the first person to think of this after hundreds of thousands of years?

Teleportation was not exactly something new nor that rare and had naturally existed in the past.

How could the Politos who lived in a world of magic and Gods have built such a door with a mindset of 'oh, let's create this very important Vault without the ability to block unauthorized spatial crossing'?

It didn't take long for the sentient door to eradicate all the nanobots. Darius had only created an amount small enough to give them entry, and their sole purpose was to eat as much as they could without defending themselves.

Darius and Miranda had discovered pretty early on that Holy Silver was capable of repairing itself, which had eventually become the cornerstone of the current plan.

It would have been quite short-sighted to leave behind a hole which anyone could enter as they pleased. That would just be giving himself more work and his enemies a free pass.

The main reason why Darius felt pressured to get through as early as possible was less the time limit specified by the Event, but more so his desire to not leave behind any clues that he and his posse were on Pokterr in the first place.

..................…

Eventually, the Holy Silver Divine Door spent an entire day repairing the human-sized hole in its makeup.

Three days later, the various 'Chosen Ones' landed in this realm and began their attempts to break through it, which, as usual, ended up futile.

A few noticed the presence of people who had come before, but none of them felt bothered by that. Since the door remained tightly shut and was as impenetrable as they had been warned, they arrogantly believed that if even then couldn't do it, how could someone else?

..................…

Darius and his two Branded Servants appeared in a white room that was pulsing with a strange energy. It was the same kind of energy in general that the door had emanated, but this one had a calmer and more soothing flavor.

This made Darius' eyes narrow. He was aware that every continent had its own power system, but it was commonly believed that Pokterr was the sole exception.

It was a place where everyone could use their own power systems as if they were native here, without any problems or hiccups.

That was why many powers would even dare to mobilize their people here despite all hailing from different backgrounds.

Of course, thanks to the existence of the Supreme System neither Darius nor his Branded Servant would have anything to fear even on other continents.

Nevertheless, Darius doubted that Pokterr had always been this way, which begged the question what was Pokterr's original power system?

Neither the Moles nor the Insects used any notable power systems, with the former being especially weak and soft, so they were often bullied by the latter.

The reason why the Insects were so widely feared was their devouring system, which allowed them to rapidly grow compared to other races, however this something unique to them, not Pokterr's overall continent.

If the Great Library of Krona had an answer to this question, then it had to be in the restricted section which Darius had yet to unlock.

The transmigrator naturally Analyzed the walls that were glowing. If he could find the name of this energy, he could try to find more details about it through Transmutation or general research.

[Gerritanium Walls - Miscellaneous

Durability: 30,000/30,000

Description: A set of metallic walls made of the rare material Gerritanium, which was could only be produced after soaking in Source Energy for long periods of time. Its properties are high durability - especially against aging - memory reshapability and conductivity for all forms of Source Energy.]

Darius' eyes narrowed. Analyze hadn't failed him, it had forked over the name of the energy that was used for creating these things which was called Source Energy.

What was this Source Energy? What properties did it have to differentiate itself from Unyris' Elemental Energy, Fallon's Magical Energy, Elysium's Divine/Faith Energy, or Pan's Heaven/Earth Spirit Energy?

Darius was deeply intrigued by this.

After all, this so-called Source Energy was able to give him who possessed Master stage stats a raw feeling of danger. It had even been able to bypass his 150 points of Intellect to make him feel comfortable and calm, manipulating his mental state.

However, Darius also noted with a smile that the first stage of the Event had been passed, and the 10 AP and 10 SP had been deposited in their character sheets for allocation.

This was to be expected, the Event merely required them to enter the Vaults. If they wanted, they could simply look for a way to leave right now, but that was not wise.

Rather, he hoped to discover more information on the contents of Vault 01 to 07 and perhaps some information on Source Energy.

In the center of this white room was a pedestal that stood opposite a white set of double doors. It frankly looked as if they were in a scientific lab and trying to see a specially quarantined subject rather than bandits here to raid.

Darius first used the Basic Morph to change his features to that of a member of the Polito Race. Unfortunately, at only 50 points of Charisma, Morph was unable to change his entire body at once, so he had to transmute a Transformation Potion to make up for it.

He then made Gunner and Xela step back as he walked up to the pedestal. It remained silent for a long while even as he approached it, so Darius placed his palm on it cautiously.

When it still did not light up despite this, Darius understood that such a simple means would not cut it. Rather, it just spoke for the ingenuity of the Politos.

It should have been impossible for them to guess how the world would look like years after their demise, and eventually, members of the various races might have found a way to break down their door.

In that case, they had to leave a last line of defense that only one of their descendants could breach. And what did the Politos have that no one could access after their demise?

It was not their biology or their culture, as - from Darius' efforts - we could see that those could be acquired by other means.

That meant that the key to entering further had to be their unique system of power, Source Energy!
