Thud! Arad walked away from the carriage as they stopped for lunch. Lydia followed him, carrying the sword that he got from Alcott.
"You sure I can use this?" She said, staring at his back.
"Your sword broke. It's the strongest we have." Arad looked back, "And that witch asked that you use a decent sword,"
"{It's Doma.}" A voice boomed from inside Arad, "{I've been teaching you about Mana since we departed. How about some practice?}"
Arad sighed, "Can you stop speaking from my stomach for a moment?"
Arad faced a tree, extending his hand and closing his eyes.
Mana is the energy fueling magic. It's an essential part of spellcasting that shouldn't be replaced. Doma told Arad that the part about it being fuel is a half-lie and half-truth. The average spell caster never uses Mana as fuel. It's the reason weak spells don't consume it.
Doma isn't going as easy on Arad as Alcott or Merlin, she's here to make sure he understand what he's doing, and have the ability and durability to control it.
