Lieutenant General Craig is considered the most formidable general of the Imperial Army. His unit, the 4th Armored Division, boasts the greatest firepower among Erebonia's armed forces.
In S.1197, his wife Liana passed away, leaving behind Olaf and their two children, Fiona and Elliot. Elliot wished to pursue a musical career like his mother, but Olaf found this not to be fitting for an Erebonian man and urged him to join him in the military. Elliot initially complied, but after graduating, he opted to continue as a musician.
Olaf had Alfin Reise Arnor and Tita Russell moved from Wilhelm Ballad's mansion to Dreknor Fortress, to see what path Elliot and Class VII would take. As soon as they infiltrated the fort, he greeted them with Neithardt, informing them that Alfin and Tita were safe and that they had to come and rescue to the two themselves.
Upon arriving at his office, Olaf and Neithardt challenged Class VII to test their strength and will. The two were defeated after a long battle; Olaf was proud of his son's growth. The battle also gave him hope that the upcoming war would not be pointless, and he allowed Class VII to leave the fortress with Alfin and Tita. He saw them off as Alan requested to chase the Merkabah, but Olaf refused. He watched the curse manifest around Alan, commenting on how it was truly bottomless.
Olaf was able to bring Alan back to the 4th Armored Division after the latter was freed of the curse.
