Using tears in the fabric of space to pass between worlds, these interdimensional travelers cross over in search of raw materials and artifacts to collect. Wearing heavy environment suits to protect them from the hazards of our reality, the Harvesters are nearly indestructible. Often times they are connected to their own world through long hoses that stretch out behind them and extend back through a shimmering gateway, bringing whatever substances they require to sustain them in our world. Lumbering but ruthless, the Harvesters are relentless in their search for anything of interest or value to bring back to their own dimension.
