You guys can roll your second fort save, but this time would have been up before you were healed. There was a 5-10 minute or so period where Arthur ran to the barracks to check on soldiers, and you guys heard the boys story.
So take it this way to determine over all status. Add poison damage first if you fail your save (13 DC Fort) (1 con for fail, 0 effect for save) then add the cures. If you are still wounded once this is calculated, please post a status update in OOC.
The poison was not neutralized, just lesser res, and cure light wounds. If you needed both, you got both.
One commoner has died. the rest have been healed by your aura. There are still wounded, and those poisoned kinda badly, but noone else is dying.
