(Meanwhile -
Cheliax is a country that is used to nonhumanoids with terrifying magical powers coming out of the forests and into the inhabited-by-humanoids-who-are-mostly-farmers regions of the country in rather the same way that is used to being invaded - that is to say, there are quite a lot of procedures in place to make sure it never happens and the reaction is usually one involving attempting overwhelming and terrifying brutality to the plausibly-hostile entities that are where it thinks they shouldn't be. You can liken it to an immune response, really.
If Dewbloom had approached overland, the immune response would have been slow. Assuming she evaded the sentinels placed on the borders of the forest - the Order of the Pike, formerly bolstered by elite army units - the news would have been spread by fleeing peasants or petty landed knights, approaching on horseback to alert their superiors. The superiors would consult their wizards and either make some doomed attempts to assassinate her, or report it up the chain of command.
- Cheliax is not, to be clear, a country that seriously considers the possibility that nonhumanoids with terrifying magical powers coming out of the forests are ever benevolent. People who panic at a ten percent chance of danger tell their grandchildren more horror stories than people who don't, and after two thousand years of an extremely vigorous immune response the chance of danger is usually quite a lot more than ten percent.
This slow immune response would nonetheless have triggered a response, should she not return to the forest before the sluggish command chain of the Chelish state organized a reaction. Flying scouts - familiars, air elementals, summoned or bound devils, since this is Cheliax - under Scries would have surveyed her, the experts on forest monsters would have confirmed her an alarune, and an invisible and heavily enchanted adventuring party with a solid number of archers would have teleported either four hundred feet above her and peppered her and her allies with arrows and spells, or right into hand-to-hand combat if they were heavy on the sword-and-polearm troops. She probably would not have ever had a serious fight between leaving the forest and her statistically probable death, which is why alarunes are rarely powerful wizards or veteran warriors - either they win, or they die.
