Stef scrambles to his feet, wide-eyed. "What's - when did - what happened?" 

Blai won't be able to understand him. Jisa answers in Mindspeech. :Lightning strike, I think - we're fine but there's a fire...: 

Vanyel's trick involved doing a weather-barrier in reverse, she thinks? Pulling heat out of the fire and distributing it evenly to the outside of the barrier, where it won't be hot enough to start new fires.

Jisa is not nearly strong enough to do a reverse weather-barrier over the entire area that now has fires in it, but she can do a tiny weather barrier around just that tree and put out the flames on its trunk. 

Oh no oh no oh nooooo he shouldn't have left them - Stef is all right, everyone is all right, but if this keeps happening then Blai will run out of magic and no one else has Healing and it's a long time until dawn - 

:You should go down into the records cache: he sends to all of them. :It's shielded - I think we have to assume this was a godintervention and it could keep happening -: 

:Maybe we should put out the fire first!: It takes a minute or so per tree to get the weather-barrier in place and pull out enough heat to put out the flames, but there aren't that many trees in range to catch fire from the burning branches of the main tree and the bark takes a while to start burning, hopefully Jisa can at least stop the fire from spreading too much while Blai is handling it. 

Create Water. Create Water. Create Water. Create Water. Create Water.

Jisa thinks the area on fire is getting smaller rather than bigger but it's definitely going to take a while. 

:I can try to summon a water elemental to help?: she offers. :It'll take a couple of minutes but might be more helpful than getting individual trees...: 

:You are the best judge of your capacities here. I can do this indefinitely.: Create Water. Create Water. Create Water.

Jisa definitely cannot keep casting weather-barriers and overpowering them in reverse all night without falling over in exhaustion! She will instead find a spot that's safely not on fire and set up a circle and start a summoning. 

And eventually some water elementals can be persuaded to help put out the rest of the fire, including some of it that's apparently burning partly underground in the roots of the dead tree. 

Jisa is sososososooooo tired (the elementals aren't ones she's already on friendly terms with and she felt she needed to give them some pretty significant gifts of mage-energy before asking them to help) and is managing to stay on her feet through sheer willpower but she's not happy about it. 

...she's supposed to follow the instructions to take down the rest of the wards before they can safely go in, aughh... 

Blai is checking whether all the fire is out by touching all the trees that might be on fire to see if they're warm.

No more warm trees! The water elementals were pretty thorough. 

Also there's no more weather-barrier now and the air is very very cold. 

:Van is - probably right - we should get behind the shields again. I think Jisa is too tired to manage another weather-barrier. ...She might have trouble getting the rest of the wards neutralized so we can go in safely, I'm not sure if you have anything for that?: 

:Well, I've still got Protection from Energy up, so if they would specifically set me on any remotely reasonable amount of fire, I will instead be fine. I could send a summon in to trip the traps if they'd do something else?:

:...I'm not sure we know exactly what they do but summoning something to trip them would be one way to find out! Er, does that - risk killing whatever you summon, is it intelligent...?: It usually wouldn't here, summoned elementals aren't entirely 'here' when summoned and the bodies they inhabit are temporarily constructed from mage-energy, but you can in theory kill trapped vrondi. 

:Summonses are avatars of the extraplanar creatures and killing the avatar just ends the spell.:

:All right. I think that's reasonable. Jisa can watch with mage-sight and see if the traps are renewable or will only go off once – most trap-spells only go off once but Leareth might be unusually good at them or something: 

The two Companions have huddled up on either side of Stef, who is shivering hard now despite being dressed reasonably well for the weather. 

...Jisa is going to sit down heavily on the nearest sittable surface, which turns out to be the burnt sooty soaking-wet trunk of the fallen tree, but she can watch traps go off with mage-sight, sure. 

Vanyel is doing his best to watch through Yfandes' eyes, which is easier to maintain than Farsight. He's asked Aroon to stop and try to arrange some branches into a threshold shape, so he has a hope of Gating in if something even worse happens, but in his current keyed-up state and without Stef nearby for painblocking he's inevitably going to mess up his mage-channels, and it'll be a mess for getting Feniss safely to Waymeet, and - in general he's just desperately hoping they can make it into the records cache without anything else going disastrously wrong. 

Blai does not "speak" "Utopian" but he knows a handful of words and he certainly can't summon anything that'd understand Infernal, any more. He summons a big axiomatic dog and points it down into the records cache. "Go," he tells it, and it goes.

The dog will be zapped with a levinbolt - not powerful enough to kill a regular human but enough to knock most people unconscious - and caught in a paralysis-spell, but that seems to be all the offensive countermeasures still active, and Jisa is fairly sure that they won't fire a second time. She's also pretty sure there are some alarms going off - including ones at a distance, she hadn't known you could do that without a system like the Web - but Leareth knows they're here and explicitly gave them permission to go in and even if he's worried enough to scry the site, he can probably determine pretty quickly why they're going in in a hurry without properly following the instructions. 

All right great can they go somewhere warmer now. 

Yes. Blai takes point and in they go. He lights up his holy symbol, it's dark in there.

Nothing bad happens! 

It's somewhat warmer underground, out of the wind, and a lot dryer. It's not exactly warm. Jisa...does not think she can manage even a heat-spell right now. There are probably heat-spell artifacts in here, that entire wall of boxes is radiating magic, but she doesn't know which ones. She's just going to huddle up in her cloak. 

Getting in involves a trapdoor and a ladder, and the Companions do not fit. To be clear they're fine for now, Companions are hardy and they can huddle together, but they can't really contribute to helping warm the space with their body heat until Jisa can Gate them in. It's a very short-range Gate but if she can't manage a heat-spell without more rest she definitely can't do that. 

Enara will at least send Jisa energy so her reserves are replenished sooner.
