On October 25th, a Lava Fiend appeared in the Fighting Arena, found the closest ladder, climbed six floors, then proceeded to enter the Whitelighter enchanting room (NE imping building 3rd floor) and began attacking the priests.
Local defense forces showed up to thwart the attack by killing said Lava Fiend.
A security hole was found after Root Cause Analysis (RCA). Subsequently, six gates and locks were installed between the Fighting Arena and Imping Buildings to prevent reoccurrence. People can pass through these gates freely, but Lava Fiends and Trolls cannot.
Village citizens and guests rejoiced!
