Most people might not be able to answer this question, not even Medisha, who might not understand those mystical things between wizards, but among the people here, there happens to be a Wild Elf older sister who is an Elemental Mage—Furlo. Furlo slightly bowed, and said methodically as if reciting:

"The Mage Tower is not just the home of wizards, Miss Roman. At the top of each Mage Tower, there is a large Resonance Crystal installed. This crystal is entirely carved from Magic Crystal and can amplify the power and range of most area spells—even extending to several kilometers, over ten kilometers away. Wizards use this crystal to make the Mage Tower an indestructible fortress, capable of striking enemies beyond visual range."

"Furthermore, the Crystal Ball set inside the tower also serves to monitor the territory. Even the most basic Mage Tower is enough to oversee all areas surrounding Fir City, making it one of the most important defense facilities within the territory." 𝙧𝙚𝙚𝔀𝒆𝓫𝓷𝙤𝓿𝒆𝙡.𝒄𝙤𝓶

"The Mage Tower also houses an Alchemy Laboratory and a public Mana Pool."

"Public Mana Pool?"

"Training Wizard Apprentices requires a lot of spell training, but low-tier Spellcasters often need long breaks to recover their spirit after casting a few spells. A public Mana Pool can greatly reduce the rest time, which means it effectively shortens the time needed to train Wizard Apprentices, Miss Roman."

"Don't call me so formally, Furlo older sister, it sounds so scary." Roman patted her chest, saying with a bit of lingering fear: "Anyway, I understand now that the Mage Tower is very important."

Furlo nodded seriously.

Brand also nodded. Furlo was not wrong at all. In the game, it normally takes three weeks to train a peasant into a qualified infantryman, but it takes almost a year to develop a competent Wizard Apprentice. With a Mage Tower, this time can be shortened by tenfold, allowing the Mage Tower to train a qualified Wizard Apprentice every month.

After upgrading, a Wizard Apprentice can grow into a First-tier Elemental Mage or Wizard, and can also cast three One-Circle Spells by themselves. Among One-Circle Spells, Magic Arrow and Magic Shield are extremely practical spells, and casting them in groups is very powerful.

Moreover, Wizard Apprentices are the foundation for many types of troops, such as Anti-Magic Knights and Phantom Cavalry, which require further training on top of Wizard Apprentices.

Building a Mage Tower requires a Magic Pool, so the Magic Pool is crucial for every Advanced Territory. Not only for the Mage Tower but also for artificial Crystal Pools that convert scattered mana into Magic Crystals, and the nests that nurture Fantasy Creatures. When a territory reaches a certain level of magical development, advanced camps can be constructed.

For example, the Flying Horse Knight camp of the Tree Elves requires a Pegasus Nest and a Star Moon Gate.

The Silver Elf Girl continued, "So generally speaking, a Natural Basic Territory will usually only have one such natural Magic Pool, but Valhalla uses its right hand to have three... This is somewhat unbelievable, it's almost like a legendary Magic Plain."

"Magic Plain?" Brand turned his head to look at Medisha, just as he had heard of this term.

"In the civilized world's magical territories, only those developed to have at least ten Magic Pools qualify as magical territories, but some natural wilds possess such power. Although they may not have ten Magic Pools, we also acknowledge such lands as being natural magical territories." Medisha continued to answer, "Magic Plain is one of them."

Brand said, "I have also heard of Magic Plain, also known as Clover Field. Such a land has a high concentration of magic, and the growth rate of Magic Plants on Clover Field is several times that of ordinary Guardian Land."

"Martha's Guardian Land is actually a type of magical land, but a more special type. Black Forest is one, as well as Flame Plain and War Sacred Land, but I've only heard of them," the Silver Elf Girl replied.

She lifted her head, "But the World Tree planted by the Lord has magic more potent than any natural magical land I've ever seen. Three Magic Pools, even our Silver Elf's ancient capital, Silver Valley, doesn't have such innate power."

"The rumored fortresses are said to be sacred lands used by the Ancestors as the final bastion against the Dragon of Dusk, with power akin to the Saint's Relics. Silver Valley is one such fortress," she continued, "but none are as powerful as the remnants of Valhalla. I don't know why this fortress is so special, but it certainly has a reason for its existence."
