Meriele marks her prey and then moves to assist the beholder and the other Zhentarim.
Melpomene casts her spell, but the drow is not affected and keeps on running.
As Mai'ngor and Xeliss chase after, a greyish, winged monstrosity swoops down and blocks their way. You recognize it as a gargoyle, "You will not hurt my love!" it screeches before moving to attack you.
It rushes forth and claws and bites at Mai'ngor, but is unable to connect.
Others can engage with the drow if they want to (especially after seeing the beholder attack Hunter)
