I find it amusing there are so many Astral sites underwater. What about Holy? Was the Ancient Temple of the Deeps the only possible?
What I like most about underwater, is that if you want to manually search, you can focus on N/S/D + Holy, and then just use Tiamat for the rest. Though Voice of Tiamat is a funny spell, it can be the best thing ever, or you can burn all your Water gems, and only get Fire and Earth for your troubles. Oh the fickle sea.
