NPC - Non-Player Character (NPC) might attack you first. Win the battle against NPC before fighting the opponent.

Swimmer - A swimming champion or ally can attack any realm in an opponent's formation that shows a coastline in its picture. This also includes realms with pictures instead of maps that depict coasts. The ability to swim is not automatically conferred to other cards, so a champion attacking a protected coastal realm must have the means to get his allies there if he intends to use allies in the round of battle. A flyer cannot choose to not fly. A swimmer cannot choose to not swim. An earthwalker cannot choose to not earthwalk. In situations where a champion or ally has several types of movement, the champion can choose which type of movement to use. For example, if a champion becomes a flyer and swimmer, they can choose how to move. The statement 'flyers cannot attack' does not restrict the champion from swimming to that realm, and 'only flyers can attack' does not mean that the swimming ability makes the champion unable to attack.

Vampire - Vampires are a special kind of champion or ally, designated in a card's text box. Not all Vampires are "Undead". Unless the card says "undead", it is not undead, even if the picture or name of the card seems to indicate otherwise. Many vampires are monster champions, though they can be of any type.
