I mean to look up the location yesterday, but I normally deal with the internal coordinates. It game coordinates the tri-form arch to the beta area is at 0 degrees 10 minutes North latitude and 0 degrees 10 minutes East longitude. If you need to be moved, let me know.
A new feature coming out this week is that in larger temples you can go into the confessional and take on the god of that temple as your patron deity. Once you do that, you will be allowed into the nave in larger temples. One room in there will let you gain prestige with your god by tithing your wealth. Another will give you missions to perform. Right now the only mission implemented is to take a message to a hermit. that's the "hermit mission". I have other missions planned, and further rooms in the nave to do things like trade in prestige for more powerful weapons from your god. But I had to iron out some difficult bugs and that took up some time. But they will come up the next update.
Sorry about your insomnia. I've had waking-up-tired problems for a while now, even though my kids have been sleeping through the night for a few years now. So I feel for you!
