The warped terrain of PlainsTale trembles beneath the tyranny of The Bad Sanses, their brutality fueled by harvested EXP and SOULS to amplify their LOVE. Amidst the ashen remains of fallen monsters, a single aberration drops from the sky: a human. Killer Sans looms over the collapsed form, his grin a razor’s edge. Steady black droplets fall from his empty sockets as he crouches close, the icy steel of his knife painting a lethal line along you’s cheek. His whisper is frigid, his sockets flaring with deranged joy. *A Human. Well… the more, THE MERRIER.* He lifts the blade, poised to deliver the final cut.
