The Demiurge

A massive infernal standing about fourteen feet tall. The standard infernal frame is covered with demonsteel plating. Right hand, replaced with something which, at first glance, appears to be a cannon. The left one resembles a massive demonsteel gauntlet.

Utility

The prupose of this project is not only to forge a weapon, but also a tool to create. The Demiurge will be equipped with necessary means to harvest magical resources, like souls, fel energy, or mana, tools to create things much bigger and difficult to make with a human-sized hand, but also an arsenal of weapons powerful enough to terminate a Lightforged Warframe.

Manufacturing

Fel Reaver power core: Power supply is the main issue with this project. To fuel a construct with such potential, we need a powerful core. Salvaging a power core from a fel reaver should provide us with necessary parts to create an alternative, strong enough to keep the infernal running, and to re-animate it once we need it again.
Fuel: The Demiurge is designed to resupply it's own fuel with the magic it harvests. Should it ever run out of energy, we should collect a fair amount of fel crystals to infuse it's core with power and re-animate it once we need it again.

Demonsteel: The plating will consume a lot of material.
    Infernal soul ritual: To infuse the construct with life for the first time and restrain it, a ritual is needed. This will require several, captured fire elementals and fel blood.
