That night, Severus learned a lot more about the world.

Tiamat told everything she knew, but probably because it wasn't her own being, she didn't know anything about her original world.

In the same way, she couldn't tell about the World Tree, or she only remembered that there was a very magical tree that could take her home, and she didn't know anything else.

But she knew very well about the early days of the gods.

But it didn't work at all, because the early gods were long dead, even Tiamat herself, and if Severus had been right, her body would have been dead long ago, not sealed as she herself said.

And it wasn't Ragnarok when she died.

Ragnarok is actually a battle to eliminate the "gods" by human beings taking advantage of the infighting among the gods, it can be divided into two parts, the first half is the various hanging ghosts between the gods, which led to the war between the gods, and the second half is that human beings see that they are expected to destroy the gods, so they continue to fan the flames, and finally destroy the gods through various conspiracies and final military means, and since then, the gods have not existed.

Hence the name: Ragnarok.

Actually, that's a long story, but in terms of time span, it's estimated that it's no less than a thousand years.

And Tiamat had died before that, or maybe even earlier.

The reason is simple.

Merlin once said that the gods were headed by Nidhogg, the god of death, and according to Severus's guess, Nidhogg should have lived in the north of England, which is now Azkaban.

Moreover, Niderhogg is not the British Hirshidiri Black Dragon, on the contrary, he is more likely to be the ancestor of the Black Dragon, and Niderhogg's history has been pushed back thousands of years compared to Severus's previous suspicions.

As for 10,000 years, it is not so, at least in the mouth of Tiamat, Severus learned that "gods" also have a lifespan.

Depending on the strength, the approximate lifespan is about a few thousand to ten thousand years.

In fact, in the final analysis, gods are just creatures that live longer and are stronger.

It is said to be a god, but it is actually a dragon!

Especially in terms of appearance, it does look like a dragon.

However, Tiamat said that the early gods were able to transform into human form and had a high level of intelligence, but it was the "gods" born from the combination of the earth's native creatures, whose intelligence gradually declined, and finally even lost the ability to transform into human form.

In Severus's opinion, they don't even have wisdom now.

For example, the current dragon.

Not to mention Severus, not even Dumbledore had ever heard of a dragon with intelligence.

However, the dragon once had wisdom, which is recognized by the wizarding world, after all, many notes have recorded the dragon language, and even the existence of dragon language magic, but now it has long since disappeared.

Tiamat, according to Severus's speculation, must have died after the crusade against Nidhogg.

When he discovered that Nidhogg had eaten the World Tree, Tiamat joined forces with the god-king and other gods who still existed to defeat Nidhogg and attempt to kill him.

However, the war was lost, and according to Tiamat, the god-king was killed on the spot, and most of the other gods died, leaving only weaker gods like her who were hiding behind.

After that, Nidhogg fled, presumably to Azkaban at this time.

After the war, humans gained magical power by eating a large amount of the flesh and blood of the gods, and some of them were even quite powerful.

Others are possessed by the will of the gods after death, and then give birth to offspring of awakened magic.

Especially with a group of humans, they stole the uneaten remains of the World Tree and a small number of rhizomes from Nidhogg, and then had magical powers.

Then Tiamat didn't know what was going on.

Soon afterward, Tiamat split this will and accepted human offerings here until one day when the offerings were gone, and she had to fall into a deep sleep until Severus arrived.

Although Tiamat didn't know the rest of the story, Severus could guess a thing or two.

It is estimated that after Nidhogg ran to Azkaban, he was defeated by a large group of gods, so he also began to look for helpers and subordinates, thus bringing in a large group of servants and establishing new gods.

On the human side, they began to study magic, and all kinds of strange things appeared, all kinds of strange experiments were carried out, all kinds of magical creatures were combined, all kinds of creatures with half-human blood appeared, and so on.

At the same time, humans don't know how to grow a miniature version, or even a miniature version of the golden apple tree, as a new world tree.

After that, Merlin knew Ragnarok, and the current wizarding world was formed.

To be honest, this big circle doesn't seem to be much different from religious mythology.

This shows that there is still something in those religions that have been passed down for a long time.

However, the religious myth is still too biased, even if there is a certain similarity, but if you interpret it according to this similarity, you will definitely be pitted in the end, and there will be no bones left.

Most religions eat people and don't spit out bones.

……

After questioning, Severus checked it again with a dementor.

It's not that you can't use the Regent to take the mind at first, but this magic still has great limitations.

First of all, it requires you to know what you're looking for in advance before you can rummage through other people's memories, just like with Baidu.

The other way is to rely on the caster's own recollection, what he thinks, what you see, this is more similar to a recommendation.

But neither of these methods is suitable for Severus, who doesn't know much about Tiamat and doesn't know what questions to ask, so this approach misses a lot.

And if she remembers it on her own, although she may be recalling some important content, the ghost knows what it will be.

Besides, any Occlumenc-Occlusion master can close his or her own brain, even creating false memories.

Therefore, most of the regents are used for review, and it is much more convenient to check and check after having a certain amount of information.

At the same time, you can also look for anything that is missing.

There are some things that the original owner may not care about, but that doesn't mean it's useless.

Just like now, Severus found a few more useful pieces of information when he checked with the Regent Mind.

This information was something that Tiamat himself didn't care much about.

For example, the location of the so-called kingdom of God established by these gods is not the ancient Babylon that Severus believes, and relatively speaking, ancient Babylon can only be regarded as a state established by their attendants.

And the kingdom of God is actually the sphere of activity of these gods, which is much larger than that of ancient Babylon.

The core location of the Kingdom of God, where the World Tree is located, is actually in the Persian Gulf, not on the current land.

Severus estimated that it should have been land, but maybe it was turned into a sea.

And the Divine Stone is actually a special stone around the World Tree, which has some magical power due to the influence of the World Tree.

To put it bluntly, it's actually the broken stones around the World Tree, and Tiamat doesn't even look at that kind of thing.
