When you attempt to learn or recall a piece of
lore, if you do not know that information, you
often know where and from whom you can
obtain it. Usually, this information comes from
a library, scriptorium, university, or a sage or
other learned person or creature. Your DM
might rule that the knowledge you seek is
secreted away in an almost inaccessible place, or
that it simply cannot be found. Unearthing the
deepest secrets of the multiverse can require an
adventure or even a whole camp
