Amalgamated constructs, or corpse dragons, are a class of demonic units valued for their physical malleability and human level intelligence. They are utilized in standard military operations by most countries, typically supporting human squadrons.

Like most constructs, they consist of colonies of microscopic demons, but their binding core is the cadaver of a drowned magician. Although their deployment in warfare is controversial and has been condemned by the United Nations since 1956, the practice is still technically legal.
