Thyrin has his primary spell book, secondary saferoom spell book, and countless scrolls. He has all of those spells you just mentioned, and if you want others, he probably has those too, he'll just have to find them somewhere.
After Thyrin fixes the containment field, you all head out, notes on the aether in hand. It's past noon, though it's difficult to tell thanks to the heavy cloud cover. You notice that the blue containment field that was once over the top floors of the tower is now gone. After passing through Grenton, it's only a few more hours of travel through light drizzle into Orussus.
The rain falls harder here, the streets are mostly empty. The lights of nearby houses are lit, people are staying inside. You keep the notes wrapped tightly in a leather sack to keep them dry. Rilithorne's tower is near the center of town, on Allimon Street, on the north side of the road near the harbor. The Red Dragon Inn is not on the way, but it is nearby, about 4 blocks away.
You reach the tower. It is 60' in diameter and looks to be 3 stories tall. Outside, swaying in the wind, hangs a sign that reads:
[smallcaps]Rilithorne, Mage.[/smallcaps]
Commissions welcome, inquire within.
Please knock before entering.
You knock.
Moments later, the door is opened by what appears to be the floating upper torso of a featureless manikin wearing a butler's longtailed coat. A voice emits from the butler's smooth, wooden head: "Welcome all. Please, enter."
Entering the tower, you find yourselves in a plush waiting room. Three different couches are artfully aranged around a coffee table, which sits upon an expensive looking rug. A small pedestal dominates the northernmost portion of the room.
The walls are hung with 3 paintings, one of which appears to be a portrait of a Human Wizard of about 30 to 40 years. The other two are landscape scenes, one of a snow covered mountain and another of a country road in fall, with leaves in many colors.
Two doors lead out of the waiting room, besides the one you just came through. A door to the east, and one to the west. Both are closed. The butler takes a position atop the pedestal. "May I assume you are present in the capacity of customers?"
