Publisher's blurb: Adrian Eldrich—Earth’s Master Mage and mystical defender—has vanished, and now the ancient evils he kept at bay are free to encroach once more! No longer bound by Eldrich’s pacts, Una, Queen of the Netherworld, wastes no time in invading to bring the Earth into her empire. With Earth’s defender’s paralyzed by Una’s malevolent curses, only Eldrich’s apprentice, Seven, and a handful of her young friends remain to stand against the Dark Lord! Master of Earth is a mystical adventure for a team of four heroes of PL 8 and one hero of PL 12. The adventure is a prequel of the upcoming NetherWar campaign arc.
