"Every spaceship has a voice; a melody of machinery and subsystems its crew learns intimately during long travels. The problem is, ever since the last mission our ship sounds WRONG. There’s something foul in the way it’s speaking to us. Barely audible murmurs. Strange whispers no machine could make. The dark corridors and vast halls almost seem to SING.
Voidseeders are a race that can interact with the minds of crew members. They will have few nests instead of one, but only one strong fighting presence at given moment. Once killed, new one will be awakened from the most developed nest.
This race will focus on whispering and controlling minds - people who will be near them will start to hear voices commanding them to do different destructive things.
