Yeah.
Desert run to the temple of Helm: Everything is known/stated to the best of his/Pollyanna's ability.
Of stuff that's occured with Alicia since Kesse:
Encounter with fey that teleports hapless dudes: Not mentioned.
Trip to Elysium and healing of tortured dudes from Kesse: Everything covered, here.
Esthan visiting her parents: Fully disclosed.
Trip to Brightwater: All is revealed
Trip to Halls of Vanquished: Not mentioned.
Redemption of Demon Armour: A solitary devil in Wetwind was killed, that's it.
Think that's it.
Edit!
Rosamund's Pregnancy: Told the group we should go visit her a month after the expected birth.
Malmuth: Sorta-harmless cult, Queen Tant was befriended, will try to help restoring the world.
Pallanth: Amaryl decided to go adventuring, quitting her day job.
Desert run mk2: Everything told up until the incident with the magic book. Deme just notes it was found to Alicia/rest of the guard. Elle is warned more in depth but not much more so. If Seira wants to bring it up any more clearly that's her call.
Seira doesn't want to bring it up.
Seira doesn't want to bring up Alicia's return, either, although if Alicia says nothing she'll tell Oberuth and Deme that Alicia went fighting in Hell and rescued people. The eladrin would say as much on his own, I expect.
Raid on the Halls of the Vanquished: Covered in full, albeit no real details about Alicia's brain drain.
Extreme training in Ysgard: The special training and the exciting battles are all mentioned. Jezebel's brief stay with us isn't mentioned, nor is Alicia's new resilience to all things not silver. Nor is her consumption of certain apples.
You guys will find out about the roc and how some guy abused Waukeen's mandate and screwed it over, which she totally hated! And now the roc lives next door and avenges Shamal, lizard by lizard.
Shar's temple on the Plane of Shadow went up in flames, fun adventure was had destroying it. There's nothing really personal about this one, either.
Success! Sword, resealed! Actually, it would probably be this open secret as no one is supposed to know or talk about but still do.
Deme's trip to Telerath, wherever it is: Full disclosure, and a mention to Donald that a shining city founded on Lathander's word exists. Of the four marks I kept, Seira, Alicia, and Donald each get one if they want it.
I'll say that I have a new Waukeen-granted lair if anyone asks, but prefer to keep the location secret. It doesn't seem to contain exciting dungeons to explore, so....
Trip to go see Dad: In general, not much is said about Deme's father unless it's brought up.
As regarding the Teleportation Circle scroll, it's now been handed over to Seira.
Visit to Rosamund and Neve and omens of a dire Winter to come: Covered in full with Seira. Will tell Deme whenever I can talk to him as well.
Battle with Shocker Lizards, encounter with Earth Elementals, repair of Portal to Elemental Plane of Earth, and Black Rock Triskelion attacks: All covered in full, will provide further info if the elementals ever find out who sent the Triskelion.
Let's see. TP Circles progress would be constantly updated as needed.
Mentions of visits to the Fiefdoms and to Kesse. In both cases, I'd cover that I'm negotiating on private matters, but if you guys are interested you can easily know which they are (up to you, in other words). The evil fey oasis would be covered in full.
Trip to plane of fire, covered with Deme in full.
The visit beyond the Amaryl mountain range and the Destroyer/Forsaken would be covered in full.
That Neve is chained and under the Hibernate spell until I can figure out what to do with her since she suddenly went nuts would be shared, but since it's very recent, you'll probably learn of it IC. Not mentioning Dannan, but anything relevant he shared on important matters (such as Kesse or the Destroyer) would be passed on as coming from Waukeen.
