A Gathering is when the four Clans meet under the full moon in a truce, to share news and stories with each other. Usually, role playing takes place in your own clan, but on the full moon*, when we all come together, you write (if you are invited by your leader to come to the gathering) your part in the "Gathering insert date here".
News you can share with other Clans:
~ new kits
~ new apprentices
~ new warriors
~ new deputy
~ new leader (though, this will be obvious, usually)
~ plenty of prey
~ warnings of twoleg activity in certain spot
~ loss of a clan member
News you cannot share with other Clans:
~ loss or lack of prey
~ sickness in Clan and cats
~ weekness in Clan and cats
~ anything else that will make your Clan look weak or like an easy target for an ambush
If you do give any of the off-limits information, your Clan could be at risk!
