So, as the [Adventure] post spam over in the Arhosa subforum probably indicated, both Whispers of War and Arhosa Ascending are ready to (re)start when desired, with the note that players using Gallants (base class) or Hanians (race) will need to rebuild their PCs. On the other hand, if the affected players would like to keep using their characters as currently statted for the adventure, that's even easier. So it's up to them.
For Whispers of War, I've worked with Gazz (Spellsinger 3, looking at crafting) and SDK (Champ 2/Savage 1, melee beatstick) a fair bit with setting up PCs, but with all the various people posting, I wasn't sure who wanted the 3rd slot in the campaign.
