Sorry to reply this much much later. Actually there are two things that bear the Gog Magog name: one is the Biblical version, written in two words, a tribe of humanoid abomination who will wage war with the remnants of humanity on the Last Days of Armageddon, and the other is a British folklore golem, written in combination (not separated, one scholar argued that it was a corruption of Welsh Gawr Madoc, meaning "Madoc the Great"). In Vali's team case, it is the latter one that they required, not the former, since it is stated that its form is golem rather than some abomination/zombie thingy which the Biblical version was depicted in popular media.
