Stef isn't a Mindspeaker but he and Vanyel have an agreement, he can let things drift up in his surface thoughts - it's a similar method to how he's learned the osanwë public-private distinction - and Vanyel can read them off him even at a distance. 

:Should I tell Jisa:  

:Sure. Remember that I don't know what the problem is - it could be minor–:

He does not have a good feeling about this, though. He heads to the other Gate-terminus and crosses. Looks for Fëanáro's mind. 

Working on an artifact.

Then which of Fëanáro's children present in Vinyamar seems the least occupied right now? 

Probably the twins! They are out fishing on Vinyamar's shore.

Then Vanyel will head that way. :Need to talk. We might have a problem. In Velgarth. Can't make contact and the Gate's down: 

Shoot. Maitimo and Leareth are there?

:Yes. At least I assume so, didn't hear word they were headed elsewhere. I haven't checked in with them since last week's chat. I don't know for sure it's a serious problem, but the fact that the Gate and the communications both aren't working...: 

:You should cast the communication spell directly: Yfandes sends to him. :Try for Leareth, try for Savil, then other people if you still can't. The Silmarils are here, you can use them: 

Right, good idea. :I can get in contact directly, without the artifact, it's just going to wear me out and I wanted to alert someone first. Your father wasn't that interruptible but if I can't reach Leareth either then I think this becomes an interruption-worthy emergency: 

Makes sense. We'll head in to shore.

And Vanyel will head for the Silmarils, the guards know him, and draw on them to cast the spell.

He can’t reach Savil. Or Leareth. Or Sandra, or Kilchas... He passes on each failure in Mindspeech. After those four it doesn’t seem worth trying for any of the other Herald-Mages, and he’s hitting exhaustion even with the power source. 

:This is officially an emergency: he admits, slumping down to sit on the nearest bench. :You need to inform your father:

- okay. 

Hey the interdimensional Gate-terminus is broken and Vanyel can't reach anyone in Valdemar and probably something bad happens.

He sets the artifact down. 

Vanyel, what might be going on.

:I have very little idea, but - remember we thought something got through the Gate? I'm worried it's related to that. That they waited - timed it like this...: 

To take out Leareth and Maitimo specifically, but not him? Vanyel isn't sure whether that makes sense. Also he's not, yet, ready to assume that Leareth and Maitimo are out, although he pretty much has to admit they're in trouble. 

He drags himself wearily to his feet. :Where should I meet you?: 

Are we safe here?

:...I don't know. I...should maybe shut down the terminus on our end, too. Maybe right now. Only downside is if: he swallows hard :if Leareth and Maitimo end up trying get home that way. But I think it's our safest bet if we want to make it harder for anything to get through:

Someone could still do it if they had Leareth, a mage who's been to Arda and can cast an unaided inter-world Gate. And Leareth is probably still rusty, which can't have been good if they came under attack, but might actually be of help here. Savil's visited Arda but not independently, and might or might not be capable of figuring it out...

Or if they have Maitimo, who can send places in Arda he's seen.

Damn it he should have thought of that right away - now he's heading for the Vinyamar Gate at a stumbling run. :I'm going to do it right now and - should I come back to Vinyamar after? Anyway I don't think just having Maitimo gets them here right away - Leareth couldn't get back, right, he needed months of research even though he'd lived in Velgarth his whole life - multiple lives–: His breath comes in pants. 

Anyone can smash the Gate, right, doesn't have to be you? Sit down, catch your breath, and then we can get out of the city. There are some places we didn't tell you about. Probably some of them Maitimo doesn't know of either though I'll have to ask people.

:–If we're just smashing it then sure: Vanyel had been thinking he could try to take it apart, but - smashing it is both faster and safer, the only downside is that it won't be repairable, and he built it in the first place – and can cast the spell unaided, if he decides he has to see what's going on.

He slows to a stop, bending over with his hands on his knees. Yfandes catches up, nuzzles him. :Oh. Stef's in Tol Eréssea. Jisa too. And Treven. If we're fleeing then I want them with us: Not to mention it's almost physically painful, being on opposite sides of the ocean from Stef - he hadn't thought it through, hadn't realized it would take this long either.

That makes sense. I will tell someone to go through and get them. 

:All right: Vanyel finds another bench and sits down, staring half-blindly at the sculpture across from him. 

He keeps remembering Haven the last time he saw it, only months ago. Imagines it on fire. Under attack by - what? Something. 

Stef? You and Jisa should come through to Vinyamar right away. We think Haven's been attacked and we're retreating until we know what's going on.

Oh. Right now - is there time to pack anything...? He's in Jisa's room with her. "Jisa, we have to go. Now."
