Monsterocalypse: Masters of the 8th Dimension - Dervishes & Tuner

Nothing will prepare you to watch as your forces are torn apart by the whirling blades of the dervishes. Even more unsettling is that as soon as they finish their dance of death, they disappear, leaving behind only the sound of scything blades. One might think to chase them while they retreat, but you will find that pathways, once open to travel, have closed, alleyways unnaturally sealing themselves shut and winding trails fading from existence. Even while you try desperately to fight against those horrible blades, the tuners float silently overhead, making adjustments to the matter around them.
