Bastion have added the Ex illis Daemon Hordes boxed set to their online store.
From their website:
The Daemon Hordes box contains a unit of eight fleaudian and demonic troops (Berserkr or Legionari, you will have to choose upon assembly). This axe bearer unit can either be quick on their feet, or hide behind their shield. While registering this kit you will be able to choose either a unit of Berserkr or a unit of Legionari.
