The cave tunnel they had just entered was lit up by rows of magic lamps - little lightning balls trapped inside glass orbs that hung from the ceiling and gave off a bluish light.
Syryn had seen such contraptions before but never had he witnessed them used so extensively, and that too for the mere purpose of lighting up a tunnel - which could have been served by cheaper means of lighting. Lightning orbs were luxury goods considered as rare trinkets that nobles and rich merchants liked to show off in their homes. The ostentatious display of the orbs struck in him the urge to commit vandalism. All it would take was a piece of rock.
"Big brother, how did they put lightning inside the ball?" Luci asked in awe.
"It's a special skill mastered by glass smiths. Only those mages with a skill for lightning can make thunder balls. These things aren't just pretty to look at, they cause damage when lobbed at an object," Syryn explained.
