Martha:
Martha peers suspiciously back at the librarian through her glasses. 'Hi. I'm Martha. And I'm with a bit a bunch of paladins and a sage and a funny little bloke on a flying thing and a dwarf.' She coughs. 'Umm. And we want to get into the Sealed Library to break a seal that Ioun created, but in order to help Ioun kill Tiamat.'
She looks around at her new friends, adjusts her glasses. 'So, can you help us? The little bloke is very convincing if you need convincing, but frankly common sense would indicate you'd want to help us defeat Tiamat. And they all look obviously heroic and paladin-like, and you have probably already heard of Sonliin.' She takes off her glasses and wipes them carefully. 'Unless you'd rather stand in our way? In my old job I used to deal with difficult librarians all the time.'
The librarian looks coldly at Martha. "I recommend against threatening me in any way, or you shall find yourselves dealing with the authorities here." He turns and looks as if he is about to leave, just simply ignoring Harald, until....
Sonliin:
"Now, now, Martha, you can get more with honey than you can with vinegar." Sonliin said. "I am Lord Commander Sonliin from Oerth. As you might have heard a short time ago, a trio of dragons followed us when we arrived from Sigil. They are believed to have been sent here by the Dragon Queen to try preventing us from foiling her plans." he said. "We desire access to the Secret Library as there is an artifact that will aid us in trying to restore balance in the universe. If you know anything about the seals placed by Ioun, Pelor or Erathis, it would help speed us on our quest."
The librarian turns, looking Sonliin up and down. "You are known to me. Your service to the Lady of Knowledge is appreciated. However, there is an issue with your request. If there were such a secret library, would its secrecy not be worth protecting? Would there not be some proof of worthiness to be admitted to entry? Why would one hypothetically allow this group entry."
He turns and looks at the dragonborn barbarian with a look of genuine curiosity when Darratheir speaks, interestingly enough.
