Nighttime is a real thing in UO. Assistant programs often turn the day night cycle off and create an always day time color even in dungeons. Not on UOAlive. We feel it helps with the immersion as the night cycles in towns and other places on the map have been customized to be quite beautiful. Dungeons however are pitch black! So there is a way to gain nightsight: Nightsight Potions sold off alchemists and the Magic Spell Nightsight will grant you night vision in dark dungeons for a limited time.
