Before the Dread Lord or his minions could step into a trap, the archlich Kel'Thuzad took a keen interest in this mysterious area of Tirisfal Glades.
He stood in the middle of the camp, with an ancient book floating in front of him. With the blessing of his magic, the book did not need any support. It was suspended in mid-air and turned pages according to Kel'Thuzad's thoughts.
On one side of the book, there are woodland energy purified by him, divided into three types: arcane, holy light and shadow.
The archlich was a little surprised to find that the original purity of these three energies was very high, surpassing any spell caster or person who used this kind of energy he had ever seen.
Such a discovery filled Kel'Thuzad with doubts, so he searched for ancient books and tried to find the sources of these three energies.
At the same time, he also remembered that Arthas had told him that there was some kind of secret in this area, but since Arthas did not tell him directly, it would be difficult for him to raise his confusion to the Lich King.
However, this cannot be troubled by the Archlich. As one of the former members of the Six-person Council of Dalaran, his attainments in magic research are among the best in Dalaran.
Coupled with the integration and application of the knowledge taught by Ner'zhul, the archlich's strength and knowledge reserves are far greater than before after being resurrected by the power of the Sunwell.
Without much effort, he captured and purified the energy in the forest, hoping to trace the true source of the mysterious influence on this land.
The book turned to a certain page, and suddenly he listened. Kel'Thuzad chuckled and marveled:
"interesting."
After a brief thought, Kel'Thuzad's laughter stopped, and his finger bones slowly traced across the page.
"Thassarian, come to me."
Thassarian, who was monitoring the surrounding activities near the town, heard Kel'Thuzad's call, handed over the task to the skeleton sentry beside him, and set off for the location of the archlich.
"What's the matter, Lich?"
"Take off your gauntlet and show it to me." Kel'Thuzad made a strange request.
Thassarian stared at Kel'Thuzad for a while, then took off the gauntlet from his right hand and gave it to him.
Kel'Thuzad pointed his finger, and the plate gauntlet made of Saronite floated in front of him. The lich moved the shadow energy to the surface of the gauntlet with a solemn expression.
After that small amount of energy came into contact with the gauntlet made of Saronite iron, it seemed to come alive and quickly tried to sink into the armored gauntlet.
Although the incident happened suddenly, Kel'Thuzad did not let this shadow energy completely escape. He imprisoned it with a single click and placed it back around the other two energies.
Strangely enough, the energy that was originally bouncing around and twisting like an insect immediately became quiet and lost its original vitality.
Kel'Thuzad stared at the plate gauntlets that seemed to be darker than before, and asked Thassarian again, "Is your sword also made of Saronite?"
…………
After several more experiments, Kel'Thuzad discovered that these shadow energies would only react with items made of saronite, and that after being exposed to it, the quality of saronite would be slightly improved.
But at the same time, the corrupting influence contained in Saronite Iron will gradually increase until it reaches a certain threshold, and even the undead cannot be exempted.
Undead under Kel'Thuzad's control will quickly lose control after using tainted saronite iron artifacts, becoming crazy and violent, and even attack their master.
After casually turning a few skeletons into piles of bones, Kel'Thuzad had a preliminary understanding of this shadow energy.
It seems to come from the same source as the shadow power that creates mineral veins like Saronite. The difference is that this power is highly active.
Kel'Thuzad's profound knowledge allowed him to understand that the cause of active energy is that when the master himself has extremely strong power and his self-awareness is hindered, he will radiate his own consciousness into the energy.
This happens when the owner of the energy dies or falls asleep.
When he was in Dalaran, he had seen active fire, water, air, and even soil, but this was the first time he had seen active shadow energy.
In any case, the thing behind this energy must be quite sinister, because Kel'Thuzad had seen countless mages who were backfired by active energy due to improper operation.
Moreover, shadow energy is still the most dangerous type, far more dangerous than elemental energy.
Thassarian's gauntlet and sword were only slightly corroded, and the superposition of his corrupted nature was almost negligible. However, the quality of the metal itself had increased a bit, which was considered a hit.
As for the Saronite ingot that was used for subsequent experiments, it was completely destroyed by Kel'Thuzad's magic.
Because there were even dense shadow tentacles squirming on the evil iron ingot, Kel'Thuzad realized that if he continued, it would most likely lead to unpredictable consequences.
If he is not on a mission now, it is not impossible to prepare for an experiment, but Arthas's order is to let him hunt down the Dreadlord and recapture Naxxramas. If he stumbles into something because of his curiosity, , he definitely won’t end well.
In addition to analyzing shadow energy, Kel'Thuzad also conducted a simple analysis of holy light and arcane energy. However, this time because there was no good experimental material, he learned that these two energies can blend harmoniously and stably. Apart from suppressing the shadow energy, no more useful information was obtained.
However, this did not prevent Kel'Thuzad, who was proficient in magic, from taking advantage of the environment to improve his confidence in completing this mission.
"Demons are masters of fel energy and shadow - but that doesn't mean they can use these two forces unscrupulously. They are the most dangerous energies in the universe."
Kel'Thuzad summoned the skull left behind by a skeleton soldier after his death and held it in his hand. A large amount of shadow power was absorbed into the skull under his condensation.
When the skull reached its limit of energy, Kel'Thuzad placed a magical seal on it and gave it to Thassarian.
"Make good use of this power, it can play a key role at certain moments."
Kel'Thuzad's upper and lower jaws opened and closed twice. Although there was no sound, Thassarian knew that the lich was laughing.
"Crush this skull or erase the magic seal on it, and the energy inside will burst out. As for how to use it, that's your problem - of course, it can only be used once. This is just an ordinary cannon fodder skull. It can’t carry much power.”
Thassarian raised the pitch-black skull. There seemed to be some indescribable and terrifying existence staring at him in its empty eye sockets, and some thoughts kept growing in his mind.
As a death knight, he quickly suppressed the temptation of shadow energy. Thassarian hung the skull on the side of his belt and added a seal with runes.
"Wisely, Death Knight, be careful with this power, it can also hurt you."
Kel'Thuzad turned around with satisfaction. He then contacted his master Arthas, because there were some things he needed to report to Arthas.
Soon, he got Alsace's response.
"What happened, Kel'Thuzad?"
