Regulus shot him an unamused look. Superior physical prowess or not, Regulus wasn't here to be insulted. "You asked if I knew how this works- not how it works. Choose your words more carefully in the future."

Regulus pointed at the runes. "These are magic incantations written in a language that imbues the magic into the parameters set by the incantations. These runes keep this garden warm enough for growing crops. The magic also helps the crops grow. But the magic needs to be activated regularly, daily-" Regulus now pointed to a specific rune, "by touching that rune. Otherwise, they cease to work."
