I suggest we give the "green ring with a very minor magical aura (divination)" to Valoria. Presumably she will be able to determine what it is then can decide if she wants to keep it or trade it to someone else or sell it.
Andalon will ask for the "Carved ivory scroll case" (60gp) which I think came with the sheets of paper, ink and pens from the unknown adventurer's backpack (female gnome cleric previously robbed by the bandits?).
Surely the "Feather Token (tree)" should go to Zorah. No telling when an instant tree would be helpful for a druid!
The potions should be allocated among us all. There's no really equitable or logical way to allocate them. The suggestions below try to reflect need / usefulness vs what the characters have already gained in the distribution of items but if anyone wants to suggest changes please say so.
Percy 1x potion of cure light wounds, 1x potion of jump
Andalon 1x potion of lesser restoration
Pipre 1x potion of cure light wounds
Zorah 1x potion of bear's endurance
Vik 1x potion of cure moderate wounds
Cyrus 1x potion of cure moderate wounds
Aris'ta 1x potion of cure serious wounds
Rook 1x potion of cure light wounds
Valoria 1x potion of cure light wounds
In terms of the money, jewellery and trade goods I think that is up to Henry to say what he requires as his share then everything else gets split evenly between all 9 characters listed above (including those in the list who might effectively be NPCs now). Maybe that ends up as an even split between 10 people (including Henry) and Henry gets Fort Stag too.
