The Galleons and gems stored in Gringotts Bank will disappear after a VE. Use dwelling or
House Vault as a storage space if you don’t want to lose your Galleons.
Favor can be bought from
Ramius at the Houses of Mystery in Knockturn Alley, or fought for in the Land of the
Shades.
To resurrect a dead House Elf, you’ll need 30 Favor and 7500 Galleons.
