Abaddon is vast. Perhaps infinite. And daemons are known as "evil without form". No reason that there are only a dozen or so known versions of daemon; there could be millions of other forms as yet undiscovered.
Maybe it's time your players have the privilege of discovering a new flavor of daemon. One that burrows through the soils of Abaddon, eyeless, finding prey by their footsteps and devouring them sight unseen.
