... there are tomes, scrolls, trophies, magic items ... but all disused, sitting around gathering dust.
Obviously you've explored the wizard's house quite a bit. I joined a couple of years ago expecting to ask a lot of questions and instead found most of my answers are already here. There do seem to be a lot monks who show up to ask a quick question without bothering to look around. But judging by how frequently links to obscure nodes appear in replies, there is also a significant number of monks who do know their way around and know where all the goodies are stashed. The tomes, scrolls etc are dusty because they reside in a dusty old house, not because they're unused.
