Frogatto will get stopped on the forest road, conveniently at a place precisely before any of the branching paths into town (aka a 100% guarantee he hits this before the town). Stopped by some new, quite ponderous-looking NPC.
imoti, [~Excuse me.~]
frogatto, [~Okay.\\nHi, I'm Frogatto. And you are...?~],
imoti, [~You can call me Imoti.~],
[~May I ask what you are doing here?~],
frogatto, [~I don't know... where's 'here'?~],
imoti, [~This is known as Tempo Village.~],
[~...\\nWelcome.~],
[~This is the main thoroughfare through town.~],
[~Our homes are nestled in and around\\nthe trees here, to the north and south.~],
frogatto, [~Okay. That sounds nice.~],
[~So if you don't mind my asking, I'm actually\\ntrying to get <em>through</em>, here.~],
[~I mean, I might stop by the town and all,\\nbut ultimately I'm headed off towards, uh...~],
[~Basically where Milgram lives.\\nHis castle? He lives in one, right?~],
imoti, [~Hmm. Yes, I believe I've heard it said that way.~],
[~But ... hmm, you may not end up getting\\nvery far, I should think so.~],
[~He would be further along the road to our west.~],
[~There is some debatable wilderness, that way,\\nbut that is the right direction.~],
[~But you would be stopped much sooner than that,\\nyes you would.~],
frogatto, [~I would?~],
imoti, [~Yes, I do believe it's best if you see for yourself.~],
[~But if you would like to go that way,\\ndo come back and talk to me.~],
[~Perhaps something can be arranged.~],
Then we have a second conversation. Frogatto can either go actually visit the barrier and see it, or just talk to him a second time, right away. Just a slight text difference between the two.
if(has_seen_barrier,
frogatto, [~So yeah, uh - I saw what you said.~],
[~There's these blue ... cubes ... in the way.\\nLike some kind of force field.~],
[~You know what that is?~],
imoti, [~I do, in fact.\\nWe are very fortunate, here, you see...~],
else
[~Yeah, so I'm curious about what you were talking about earlier.~],
[~You said I won't be able to make it very far? What's up?~],
imoti, [~Ahh, if you have not seen it, shortly\\npast here there is a barrier.~],
[~A 'force field' of sorts, made by magic.\\nIt is blue. You cannot miss it.~]
)
[~There is a great witch in this forest;\\nquite nearly in the town, itself.~],
[~She is known by the name Prospera.\\nShe has offered us her protection and guidance.~],
frogatto, [~Okay, that sounds like a swell deal, but uh...\\nsurely there's some sort of catch?~],
[~Is she your ruler?~],
imoti, [~Hmm, hmm. Quite clever of you.\\nNo, she is not our ruler.~],
[~We have a mayor by the name of Truggle.~],
[~However - "What's in it for her?"\\nShe does not seem to want to rule...~],
[~But she often needs help with various errands.~],
[~We are happy to do that, because she helps\\nin ways we could not hope to do.~],
frogatto, [~So ... she made that force field?\\n<em>She</em> did that?~],
imoti, [~Yes~],
frogatto, [~Dang.\\nI wouldn't know the first thing...~],
imoti, [~I expect you would like to know why she did that, but I would rather defer this.~],
[~There is a fellow in town named Whatran who\\ncan give you the ... long story.~],
[~In the meantime, suffice it to say, she is\\nthe only way you can get rid of those.~],
frogatto, [~Okay... so I just go ask her?~],
imoti, [~Essentially, but I expect she\\nwould not trouble with you.~],
frogatto, [~Huh?~],
imoti, [~I do not think she would receive you.\\nShe is a bit standoffish.~],
[~...~],
[~However... I believe she would be of a different\\nmind, if you gave a favorable first impression.~],
frogatto, [~You think I can't get by on my natural charm\\nand personable manner?~],
imoti, [~I am supposed to be delivering something to her,\\nbut I would rather be spared the hike.~],
[~If you deliver it for me, instead, I think being\\nthe bearer of good news would help ... ameliorate things.~],

not sure if we’ll just have him literally have it on his person, or have frogatto run to some house in town or something - maybe out to the docks?
