"Ok, Nurlan and Charlan starts. Each two hours, there is a change. Nurlan will be replace by Somac. Charlan by me. Somac by Tor. Me by Tenebrynn. Tor by Ashnar. Nurlan and Ashnar have both half watch, the others have full, and the two bookworms will be able to study at the end of the night, and I don't think it takes more than two hours to prepare yourself, so at least one of them will be aware at some time. Seems nice with that? If so, I'll get some sleep now, because my night will be cut in two."
