Is R2-D2 in it?
How long is the adventure section?
Page wise I mean
There's no single list of temples that I can find, unless I'm missing it. But there's a few pages on Wards, and there are temples mentioned in the text.
The Sea Ward mentions House of Wonder, House of the Moon, Tower of Luck, Temple of Beauty, House of Inspired Hands.
I'm not really (as in at all) a FR scholar;I don't know what the Plinth is or where to look for it. Sorry!
Dunno! That would involve parsing the entire text for keywords.
It'd be in the Trade Ward, it is an Interdenominational Temple, which is likely why any acolytes of none evil deities get the full benefits of their background feature in Waterdeep (if it has been rebuilt, it got destroyed in 4e).
Also is there a section on backgrounds or renown in the book?
Any new monsters?
There's about 30 pages of monsters and NPCs. Mainly NPCs rather than monsters. I like the drow gunslinger, the gazer, and the walking statues of Waterdeep.
Any mentions of setting it in Eberron, Ravnica, etc..?
