Lieutenant David Whitlark was a marine officer stationed to the Mars Outpost.

He promised to Colonel Graff that he'd give some reports by Tuesday but in the meantime he discovered the old video game Doom tat was curiously similar to his reality, and postponed them. Graff complained by e-mail and Whitlark apologised, but mentioning that the game would be made for cell phones.

He needed the yellow key of the Entrance sector, and Jah Raphael mistakenly wrote that it was in SW corner of the sector. After Witlark searched in vain, and complained to Raphael, he admitted his mistake and that it was in the SE corner. While Whitlark went to look there, he met his death.

After not returning for several days, Colonel Graff wrote to all personnel about his disappearance.
