I'm reviving an idea I've seen here before. The topic in General about doing a Giant themed Pilgrimage reminded me of it and I couldn't find the old thread.
Let's imagine temples, again, or for the very first time. :)
Imagine there's a temple for each of the Giants. Each temple location and appearance matching to fit the persona of the Giant. After the temples are in the world, there could be phases or levels added over a period of time, so they could be something that grows with Ur.
Phase 1, a simple quest at each to enter the temple to the Main floor.
Phase 2, a puzzle quest maybe to unlock another room.
Phase 3, the glitch must discover thru trial and error the *right* combo of items the Giant requires in donation to open the next room/level. Like the Ghost quest, the donation would be somewhat unique to the glitch so that one person couldn't give a spoiler. At level 3 you should be able to do it yourself.
It would be a longer multi-part quest and gives glitches an opportunity to learn more about the Giants as they go along. Glitches could also invent their own pilgrimages. It would also provide a focus for travel to the far flung areas.
I've collected temple design inspiration HERE or HERE2 or HERE3 or HERE4
That's all I've got... tag, you are it. Imagine.
