A very cool moment as Ragnar, still very much a sickly man (that part wasn't a trick), pumped up his intensity for one final act. And that shot of Bjorn throwing up his arms, sending the vikings in to plunder the streets, was awesome.
Answer Wiki. Incubus is a mythical creature, a demon in male form who preys upon sleeping women in order to father children. According to Malleus Malleficarum, demons are infertile and unable to procreate (due to the fact of them being dead) so they came up with a proxy way of making people.
From NetHackWiki. Wumpus, q, is a reference to the old game called Hunt the Wumpus. It is a very slow but strong animal that can cling to ceilings. This attribute allows it to be generated over and move through water without drowning or being relocated. It is a rather rare creature but not among the rarest. Should you ascend a game, you are pretty much guaranteed to meet at least a few wumpuses.
