The presence of the Mythal made the Githyanki hesitate.
But it could not stop their attack, because the Githyanki understood one thing very well: no Mythal could run for very long at present, and forcibly activating one could easily drain the energy in the Elemental Pool instead. Mythals had first emerged from the spell-weaving techniques of the High Elves. After passing through the Silver-Earth Era, the Ismat Era, and the age of the Arcane Empire, their construction had gradually approached perfection. However, the larger a Mythal was, the more energy it consumed to operate. (Note: some spell information about Mythals is available on Baidu.)
Mythals primarily provided constant spell enhancements.
Even during the age of the Arcane Empire, ordinary Floating Cities could not use Mythals to maintain Energy Protection Field shields unless they were governed by a core Archmage.
At present.
The Mythal covering the Arcane Tower provided the following five spell enhancements—Improve Resistance (permanent), Protection from Evil (permanent), Bless (permanent), Sharpen (active), and Grace (active).
A Mythal was a special kind of domain power.
Refined by several civilizations in which arcane magic had flourished, a Mythal was like a net into which immensely powerful spellcasters continually wove all manner of functions. The Mythal currently grafted onto the Arcane Tower was still relatively low-level. It had only three permanent spell effects and two large-area spell effects that could be activated, and practically all of them were intended to counter demons. To truly fulfill the role of a Mythal from the age of the Arcane Empire, Goria and the Fallen Witch still needed to weave in special abilities such as an Antimagic Field, as well as enormous-area spell attacks that could be activated temporarily.
The most powerful Mythals could even allow ordinary people within their range to cast spells at will.
