We could stand near the border and see if anything happens to us when the divine magic comes?
Or leave a bowl of water -- or just some water in a hole in the ground -- and see if the water gets transformed to sand or magically dried. Or if nothing happens and it just wears away.
... I wonder what it does to trees or saplings or seeds?
- Among Morghur's reputed abilities is that anyone casting spells near him as a change of turning into a Chaos Spawn. Just something to keep in mind.
Ah, right, yes. Obvious issue is obvious.
I'm not sure if it counts as 'experiment using magic' but can Mathilde further observe and get more data on the divine magic replacing the rock with sand?
There's no other data to gather. Mathilde has no implements or techniques for measuring Divine magic.
Well, we could try seeing if Ranald is willing to steal this divine energy.
Maybe via using the Coin or something, such as by having it near the border when the divine magic activates and transmutes stone. Though, uh, I'm... not actually advocating this. Even if it works perfectly well and has no danger to Mathilde nor Ranald, I feel like with a demigod in the area, we'd probably get a very instant and unfriendly response even if it worked, so. I mean, if casting magic is dangerous, then casting divine magic is dangerous too. Much less directly trying to steal said divine magic. So, no. Not to mention we don't quite know how to reproduce the circumstances where we stole from Mork, at will.
We could plant some seeds in the ground by the border, and see what happens to them when the border expands?
And then dig up the seed and sand, and store it away; then later when we're back home we experiment with it.
... Probably should gather up a ton of that sand anyway. Maybe we'll be able to grow something in that sand, back at K8P or the Colleges.
... We could also try planting the maybe-Athel-Loren-acorn at the border or inside it. Or throw it at Morghur at see what happens. But, uh, that's... yeah, no. No. I'm just half throwing ideas at the wall, half thinking out loud with free association or anything that comes to mind...
