The Titans of Ark are godlike beings believed by the denizens of Erfworld to have created the world.
The Titans of Ark are godlike beings who created Erfworld. At least three in number -- although there may be more --- and apparently serving as some kind of pantheon for the folk of Erfworld both for purposes of iconography (since they seemed to be depicted in every throne room or command centre we've seen so far) and for purposes of blasphemy ("Titan's Testes!").
They are also responsible for the creation of the Artifacts that play such a crucial role in the realpolitik of the world they created.

For most intelligent beings within Erfworld, it is taken as a matter of faith that the Titans created the world. Furthermore, most characters seem to believe that the Titans, either directly or indirectly through their design of the world, are responsible for the seemingly spontaneous generation ( or popping ) of units, cities, and animals.Erf-b1.5-p020
It is also widely believed that the Titans have a plan or purpose in mind in their creations, and much of the conflict around which the Battle for Gobwin Knob was based, and a more overarching conflict between royalty and non-royalty, seems to arise from disagreements over the interpretation of this purpose/plan.
