You don't need to reload to before entering the temple, just before using the teleporter pad at the end.
There is a waypoint shrine in the middle of where the corridors cross between the library and Amdusia' chamber, and the chamber with the bedrooms upstairs and the teleporter to Sentinel Island. You can use that to teleport anywhere in Broken Valley (closest to the fjords entrance is called South Valley, IIRC) and when you are done, to return to Maxos temple.
