Publisher's blurb: Pyre, the flame of Eston, was once known as Cyre's greatest church dedicated to the Silver Flame. Standing like a fortress over a dark entrance into the underground realm of Khyber, the church protected some of the most vile artifacts ever to be recovered from the minions of the daelkyr. Unfortunately, like everything else in Cyre, the church was destroyed on the Day of Mourning, and while the divine wards of the church's vaults remain intact, they are left undefended from the machinations of the daelkyr. Now, the Church of the Silver Flame has called upon the Diggers' Union to assist them in the recovery of the dangerous artifacts contained within Pyre's vaults. Along the way, old friends and new ones will assist the adventurers as they fight their way past living spells and terrifying aberrations known as the grell. With harrowing, easy to run, aerial combats that take place in dark chasms and fire infested pits, this adventure should prove to be exciting for both DMs and players alike.
