Threat from Nowhere is a 1st edition Dungeons & Dragons
tournament module written by Len Lakofka and run at
GenCon 1982. It was the third round (“Round 4006”) of a
three round tournament module written by Len. The first (the events of which are referred to in “The Story So Far” section below) is lost to history (or at least has not been located within the Lakofka Archive to date), and the second was A Minor Threat (“Round 4005”, also released by the Lakofka
Archive).
This module contains various pre-generated characters used
for the module at GenCon. Each of these features three
different levels, apparently intended for use in each round of the module. As such, it is suggested you use the third of those for this module.
