Blood War** is a massive, multi-tier, high-level campaign set within the Forgotten Realms setting. It spans millennia, from the Pact Primeval (see Fiendish Codex II – Tyrants of the Nine Hells, pgs. 4-5), all the way through its resolution during the time of the Spellplague and its aftermath a hundred or so years after.
NOTE: Though the campaign uses official canon from 1st through 5th editions of D&D, the campaign uses 3.5 edition game mechanics and errata.
The campaign requires gestalt characters (see Unearthed Arcana, pgs. 72-76) with a starting level of 15. All official Wizards of the Coast Dungeons & Dragons material is allowed – handbooks, magazines, and WotC web content. There are no alignment restrictions, and monsters are playable as classes as well, subject to DM approval, using mechanics from the Savage Species handbook. In fact, outsiders are actually welcomed wholeheartedly, such as angels, celestials, demons, and devils, and can be one “side” of a gestalt character.
Needless to say, this campaign will take players into epic levels.
