This module from the first season is very fun to DM. It takes some DM skill to get the group going, and to keep them on the right track. Also in part 1 there is the danger of characters jumping aggresively on the supplied "distraction" in one of the NPC's. All in all its a well balanced module between some research and RP at the front and a rewarding combat as a conclusion.

The feeling you get throughout the adventure is a chase scene into the unknown. Very scary for the adventurers if done right by the DM. You can create this scary Libary tomb scene if you controll the information given in the module. Be carefull with the creatures in that scene, they can easily be deadly, with their resistance against most damage types.

I already ran this 3x and it is still one of my favorites to run. It gives new players a chance to get a taste of roleplaying and advanced players to shine in giving direction to the group. The reward in the end is a bit low given the challanges they face, but I'm pretty sure that a full 2nd level party will be happy once they've beaten the boss.
