The big null cometh (PDF) is my version of “The Worm Hunts” scenario from the official Frostgrave book.
This one is probably more suitable for higher level Wizards, maybe 14+? I seriously don’t know since it has not been playtested yet, but I think the Big Null statline and special rules is pretty tough to deal with. We will test it later. Now we are busy with introducing “ulterior motives” to our games…more on that later.
