And still another 15 minutes of D&D brainstorming

I have another session coming up on Friday! I don't think my party reads my blog. If you do--STOP IT!

There is only one door you need to open
Think of what kind of question may lead you to a song these kinds of guards would know
Examine the words carved in the other door (DC 10 to find woolen fluff in them and then DC 15 to see small worn areas in blanket the scholar is using). No fluff found in the word knowledge.

More rows of chained books shelves. In this room there is no light. Need to find a way to see.

Random book generator
Roll D20 to find language. 1-16 as listed here. 17 and 18 are Common. 19 and 20 are Elven.

There is a large ornate mirror across from the staircase. In the light it is blood red. It shows the room as it is, but the gem is at the bottom of the pedestal. The gem must be placed there and have the blood smeared on it in order to be destroyed. The duplicates can't be called forth until it's placed in the right spot. The duplicates emerge out of the mirror.
A large blood red gem stands on a pedestal in the center of the room

Rune of Confusion surrounding the pedestal: DC 15 to find, DC 15 to disable; affects all targets within 10 ft., DC 15 save or become confused for 1 hour
Under the gem is a note: The key is found within a royal's head, use a prick to paint me red, be aware of what you spurn, for what you give shall be returned.

A duplicate of whoever puts the blood down will need to be fought. Once destroyed, the gem is destroyed and the curse is lifted.

Door to top level and lighthouse: The door is filled with holes about the size of a dagger blade. When a dagger is inserted into a hole, it makes a specific and unique tone. You have to play the first bar of the national anthem to enter. Royal blood also opens it.

There is no light on at the moment. It's a magical light that knows when it needs to be on so someone just stays with it to look out for ships and raise alarms if need be.
One guard at the lighthouse level sleeping in her bed roll. She has basic supplies with her:

Longsword, 10 silver, a map of the area, a bottle of ink, an ink pen, a lamp, 2 flasks of oil, 5 sheets of paper, a vial of perfume, sealing wax, and soap, studded leather.

She's a beautiful Elven woman with long flowing blonde hair and delicate features.
Daeven
Intelligent, arrogant, loyal to queen Mileyth (knew plan, guards knew that the queen ordered them to sleep but not details)
Will talk down to the adventurers
Will be somewhat impressed though that they managed to get through everything without having been told how
Will be suspicious of them if they mention Durogark
She is willing to tell the adventurers what has happened, but only away from the guards

The coast is a refreshing sight after spending time in the dark. Waves splash quietly on the sandy shore, the sounds of gulls overhead give the sky life. The sweet smell of seaweed washes over you, invigorating your sense of adventure.
