While it was unclear precisely what Convergence was (At least until Dead Space 3), both the Unitologist dogma, Nicole's statements and some developer comments seemed to indicate that it culminated in the creation of " something greater " which we now knew that it was another Brethren Moon.

Isaac, you have to make us whole." This echoed what she said in Dead Space during Isaac's encounter with the Red Marker. When asking what it was doing, Nicole simply replied, "What it was made to do. The Marker flashed and emitted a noise like a fog horn followed by an upthrust of wind drawing the Necromorphs up into the air. During a holographic video message from Tiedemann, the sheer mass of bodies near the Marker triggered the start of Convergence. Nicole appeared and told him that they are coming to the Marker as Convergence was at hand. When Isaac arrived at an overlook above Marker 12B's chamber, he was positioned above a mass of Necromorphs at its base. To them, the signal only manifested as noise. People of lesser intelligence are simply driven mad by the Marker's signal over time. Logs found by Isaac throughout the course of Dead Space 2 revealed that, to highly intelligent people such as Nolan Stross and Isaac Clarke, the Marker's signal manifested inside their minds as 'blueprints' for the construction of a Marker. The signal implanted specific codes into their brains at an earlier time - in Isaac Clarke's case, during the events of Dead Space - and these "blueprints" are extracted from them during sessions in the NoonTech Diagnostic Machine, using a needle through the ocular cavity (The eye) into the patient's brain. The team used Isaac Clarke, Nolan Stross and at least three others (Clarke and Stross are called Patient Four and Patient Five, respectively) suffering from mental illness from a Marker's signal as the basis for their research. Many details regarding the construction process remained a mystery, but various logs suggested that the Marker was either "grown" in mineral bath or physically constructed using machinery. Marker 12B was built by a team of scientists and engineers stationed on Titan Station under the orders of Director Tiedemann.
