And they prepare.
Jisa gets the inter-world Gate down. Does a couple of tiny practice ones. Collects Vanyel and sends him to Lórien. Uses the opportunity for one final conversation with Moondance, to coordinate on their plan - he has to be ready every day for a candlemark around noon, since they don't know what day they'll arrive within a reasonable range - and to check that he's sure. He is. There are hugs and tears and gratitude and then she puts it out of her mind, she can hurt about it afterward, right now she has to focus on preparing.
The Quendi songs for faster reflexes do help with Gating and Stef can push it even harder with a bit of discreet Bardic and they get it to the point that he only needs around five seconds of song and it doesn't have to be loud. Jisa practices threshold-less Gates. Gets it down to two seconds or so without any reflex aids. With the song it's one second, and if it's below her at the moment she and Stef manage to tackle Maitimo then they'll be through it less than half a second after that. She can keep her mage-gift concealed until the instant before she starts.
Fëanáro makes her an artifact. It triples her comfortable Mindhealing range and gives her almost the same precision at the edge of it as she has from right up close. It's not exactly the same thing as doing it through shields, which she attempts to practice using someone inside Van's Work Room while she's outside. The shields in the way reduce her effective range but she can still do a simple set-command, and more to the point a subtle and hard-to-notice one, at twenty yards.
Maitimo's assistant Larya helps her find a few volunteers who are willing to risk dying, despite Mandos' current absence, in order for her to test her set-command. It works. She practices that one in particular until she can scream it out in Mindspeech in about a quarter of a second, even Maitimo shouldn't be able to react that fast.
Stef trains his Bardic 'Sight' as well. Drills his Bardic 'shield' over and over again, holding aggressive boringness over himself and Jisa. Jisa practices concealing her own Gifts.
Six weeks later they can Gate to a small town in Rethwellan and travel out into the country to meet a down-on-his-luck merchant named Arnat, who will take them in his slightly decrepit wagon and introduce them on the road as his two nephews helping out the struggling family business. (Jisa, with her chest bandaged flat and short hair bleached to a rather hideous ginger and enough dirt on her face, can pass as a slightly chubby boy of fourteen or so whose voice hasn't broken yet. Stef's red hair also gets hacked off and dyed an ugly mud-brown, which is almost the worst part, but everyone is making some sacrifices here.)
They make it past the border with Valdemaran almost without remark - no, Arnat didn't know his nephew was Bardic-Gifted, that's wonderful! And he's always heard Valdemar is the best place for Bards, too, good thing they're headed to the capital, maybe the boy can meet some. He hears things are so much better here since Vkandis helped with the war against the foreign invaders.
And then it's only another week to reach Haven.
