(As Glimmer recounting to anyone who thinks to ask)1
"It was a nice morning when we set out to solve the Shrine. I believe it was Sapphire who had caught word the people of Hope Arch had begun to feel the strain of insufficient wet clouds for their population. Anyway, we had been told to "Find the Phoenix"." Glimmer absentmindedly strokes a shining rock-like thing
"As Chert had disappeared into the breadbox earlier in the morning, Sapphire and I set out together with Horse Richard, towards the pillars. Turns out - chert was there already, he's got quite the knack for showing up when something is about to unfold… and a pleasantly impulsive mind as well!" The dragon turns the shiny object over, holding it up towards the sky, then spends a solid minute admiring the light play with the sequins in their poncho.
"Ah, yes, as I was saying, chert 'booped' the obelisk, which had these weird symbols on it. And then the symbol started glowing! There were four sides, with three symbols on each, all different. Turns out, we could make them glow, or stop, by touching them, though no more than one symbol per side could glow at once. Nothing much was happening from just pressing the one obelisk though, so we decided to investigate the 17 other ones. Letting Richard lead the wagon, we went through the obelisks, drawing up a bird-shape, until it was juuuuuust right, and then the sky came down. He's a HUGE bird, and he gave me this thing. It's a star." Glimmer proceeds to try out various placements of the star within their hoard, working to get the reflection right. Upon further prodding for details, they will quickly list off the following:
"When two of the same symbol between two obelisks were glowing, a glowing line formed between them. With some fiddling we managed to make something that looked like a phoenix from above. Icould tell you exactly how we did it, but according to Hope 'the obelisks move' so it seems clear the solution will not be the exact same. Like all shrines I know of, I suppose."
