The riddle? Not that hard really.
Any form of that is a valid answer. Since I kind of have to answer for them all, they all get the +2 to combat rolls for the next day.
Those sprinting to the gate included The Professor, Lyric, Faris, and Zilmora. All but Lyric made it there quickly and gain +2 to defense tomorrow as well. Lyric stumbled and missed out.
Those sneaking are Tsavani, Syntax, and Astrid. They all got there quietly while staying in the shadows and got the +2 defense.
Those just prepping for the battle were Sir Gareth, Mori'an, and Wolfrik. Sir Gareth and Wolfrik walked in so confidently they were able to intimidate the lava beast and gained the +2 defense. Mori'an didn't appear to be concerned either way.
Astrid passes her poison roll.
