Aliens Phalanx Mmpb

"Ataegina was a flourishing medieval world until demons turned it into a living hell. Swarms of lethal creatures with black husks, murderous claws and dreaded 'tooth-tongues' wiped out ninety percent of the population, driving survivors into remote mountain keeps. When young warriors discover a weapon they can use against this hideous evil, they journey to Black Smoke Mountain to kill the Demon Mother."
