Returning to Solvi's the next day, Eldrian watched and recorded her adding just a few lines to the voidstone. The inscription was so basic, yet, it took her half the day.
When she was done, she was drenched in sweat and beyond tired.
"That is it for today." She mumbled as she headed for her room to sleep.
Smiling wryly, Eldrian understood why she was so tired. While what she had inscribed was simple, the amount of mana she had constantly pumped into the inscribing pen was insane. She had run out of mana more than once during the process.
Which had led to her needing to make use of mana crystals to continue her work. Something Eldrian was shocked was possible. Refilling one's own mana store with a mana crystal he hadn't thought would be possible for normal people (static magic users) but she had proved that it was.
However, it was truly expensive, and she had used her own crystals to do so.
