The hair on the back of Osiris' neck stood up, and he felt a shiver go down his spine in spite of himself. He grabbed Anubis' arm and started pulling his son towards the Sunbarge.
"Set is still down here, for obvious reasons" Osiris said, doing his best not to just break out into a run. "And he's not in a pleasant mood."
This was a very, very bad situation, Osiris reflected as they neared the dock. He needed to sail out of Duat on the Sunbarge. It was as tied to the cycle of death and rebirth as he was. Without anyone to ressurect and pull him to the surface, the boat was his only definite way out of the underworld. While he could almost certainly find another way out, Osiris wasn't looking forward to trying that with Set on his heels.
"How do you usually get out of here?" Osiris asked Anubis. His son wasn't dead (and Osiris intended to keep it that way), and so there was a good chance Anubis might have been able to just leave.
