I admit I'm somewhere between Claire's idea, and the Idea of Demonic Lords.

We know as a fact that there are Elder Demons, who contain power rivalling Mahjarrat. In some ways, it's arguable they excel.

Thammaron was one such demon, and the only example we have to go by currently. He laid seige to Uzer, and almost suceeded in taking it. If there were one less Golem, he'd have managed to destroy the entire opposition.

Keeping in mind Zemourgeal failed twice to take Varrock, and Lucien failed a third time in between (And they both had massive armies of undead, Magi, or Knights) it can be disputed Thammaron's third age attack excelled even past Mahjarrat in potential.

However, if this is truely the case, how did Zamorak tame the Demons to his will? I believe, in Zaros' Empire, the majority of Demons were bound in contract to Thammaron. It'd make sense after all, considering his supposed presence in Zaros' inner circle.

Easily put, Thammaron was promised an entire city to rule over. This may have been enough for him to make a new contract with Zamorak.

Tl;dr

We have Elder Demons that serve as Lords of the Race, who each have their followers bound to them by contract.
