Immortals of Blackmoor:
Okay, this is a project in progress.
I am working on finding Mystaran equivalents to the deities of Blackmoor.
However, since most of Mystara's immortals achieved immortality after
the destruction of Blackmoor, most of the deities of Blackmoor are likely older
Immortals. Some of these may have faded after the Great Rain of Fire, or have simply
kept a low profile. The Immortals who were active at the time of blackmoor and who also
are widely worshipped in AC1000 are detailed here
The Human Pantheon of Blackmoor
The Elven Pantheon of Blackmoor
TheDwarf/Gnome Pantheon of Blackmoor
This topic is being discussed further here.
