Here's a rehash of what you have done in Mantor's Library already.
On the way there you had a fight with a goblin wizard and a bunch of hobgoblins.
Then you found a man who was completely mad, but maybe there was some truth in the mad things he said. They are found in the INFO thread (last post, day 12).
You also found a number of books, some had interesting information from the time before Phlan's fall. Those books have been brought to the Council (for a nice reward). The most interesting passages are also found in the INFO thread (right below what the madman said).
There has been a small group of outcast kobolds. Pitiful creatures. They warned you about dangerous puddle-lurking slime-creatures in the library's garden. You havn't done more than a quick look into said garden.
You also found another dangerous creature, a basilisk, that turned Elrohas to stone. After defeating it, you brough the statue back to Phlan to rescue him. Elrohas then parted with the group, having had enough from adventuring for a while.
Bye
Thanee
