General of the Army[note 1] Ambrose Caiden was a senior officer in the Sovereign Colonies Armed Forces who was involved in the early stages of the Black Marker project. In 2314, he informed General Spencer Mahad that the Sovereign Colonies Council decided to invoke Scenario Five and all materials and personnel connected to the Marker research had to be destroyed.
Despite the implementation of Scenario Five, some of Caiden's records pertaining to the Marker research were still extant in 2508.
- Ambrose Caiden's rank is abbreviated "GOA" in Log:Last Contact, while Spencer Mahad's rank is abbreviated "GEN". Common military abbreviations imply that they are General of the Army and General, respectively. Additionally, the fact that Caiden is giving Mahad orders directly from the council implise seniority in rank.

- Dead Space 3: Log:Last Contact - "Everything about the markers - all research, all replicas, even the black marker - must be forever buried. All sites are to be shuttered. All involved planets are to be blacklisted. Everyone involved in the marker program, from Aspera to Aegis VII to Tau Volantis are to be executed."
