Blackmoor dungeon history

[gsvenson]

Apparently there were a few things in DA4 that Arneson was unhappy with, but it has never become clear what those things were. It is possible that this rumour has been emphasized by ZGG as part of a stratetegy for selling the "real DA4" at some point in the future. This never happened though.

While Dave Arneson said he was not happy that Dave Richie did DA4 on
his own and that he would have made things flow a bit differently had he
been involved, he accepted it as Blackmoor canon after it was published.

I think that dealing with the results of DA4 was actually a big part of the
ZGG era material for the Blackmoor setting. A number of modules in the
MMRPG were centered around facing the Afridhi, for example. You have
the whole Brotherhood of the Greenwood thing, too. That all came from
DA4.
