1) To the south of Vaulthill in the cave under the tree (2 boncas) - a small map, shows less than half of the world

2) In the library near the Castle -  more full, but it doesn't show the way to the Temple, nor the Temple itself.

3) The old Hermit (north-east) has the best map. The Temple is there, and islands too. Both big islands have bonuses.
