This Imperial Fists Astraeus was part of the Assault on Zybos diorama at Warhammer World.
The Astraeus is a super-heavy tank, similar in form to the smaller Repulsor transport in use by the newly created Primaris Space Marines. It mounts a formidable array of weapons, designed around a pair of immense macro-accelerator cannon. Providing a stable firing platform for these temperamental weapons are banks of enhanced repulsor plates, allowing the inexorable advance of the Astraeus to continue unhindered by hostile terrain or the vain defiance of the foe, while its layered void shields can shrug off even the most devastating weapon strikes.
