Knight is a creature in Dwelvers.
This being separates himself from the rest of the creatures thanks to the obvious fact that he is a human and does not live underground. In the dungeon there are so-called portals spread out that leads to the surface. These portals are the only way to enter the underground from above or vice-versa, therefore the humans have set out knights to guard these portals. For every portal claimed, knights will come down and try to reclaim them by killing off any intruder.
