Here come the house elves now, trouping down the corridor, bearing the pieces of Silmeria's armor that had been left behind in the Great Hall. Lezard beckons Snape into the chamber to clear the doorway for them.

"Leave them there," he directs the elves. He's quite pleased that his guess about the armor has paid off. Now he has something of Silmeria's, since she took something that belonged to him. The elves stack the pieces of armor against the wall in the place Lezard has indicated, and hurriedly take their leave. They don't like being around this chamber.

It's not hard to see why.

He's made the room(s) into something very like the study and laboratory he'd kept at the heart of his first Tower, the one outside Flenceburg. There are large glass vessels, large enough to contain a human though they're currently empty save for a viscous green fluid that is aerated by pipes. There is a work table whose surface has been scarred by chemicals and burns.

There is also a small sitting area, where once Lezard entertained Tyrion, and here he invites Snape to sit.

"It's kind of you to have thought of me," he says, "but really, your warning did come too late."
