Arco Olaf was present when first contact was initially made with the Homo Insipiens of Earth, and after having earned their Cryogenics Doctorate from Roddenberry Prepatory Academy of Medicine they have joined the expedition to return and bring the venture full circle. Arco has long struggled to put their Doctorate to fulfilling use, having been relegated to menial duties at the Sacred Heart Nebula Station, but soon discovered the much more appealing missionary work of the Critical Earth Expedition. Now, with the fate of the Earth primates in the balance, Arco hopes to right the wrongs that were borne upon them by the Homo Insipiens.
