We were commissioned to put together a Heirotitan conversion using the Warsphinx kit, and we did - leaving all the parts required for a complete Warshpinx, too!
The inspiration for this Heirotitan conversion was drawn heavily from the Egyptian influence present in many Tomb Kings miniatures. This is most evident in the Anubis jackal head on the Heirotitan and the sun-cobra symbol of Ra on the staff.
