-Yugoloths Reconcepted by James Wyatt
[SBLOCK]-The Demons have welcomed their wayward cousins back into the fold. Once Neutral Evil Mercenaries in the endless Blood War, these Fiends are now TRUE DEMONS. They have dropped the schismatic-loth from their surnames: Mezzoloths and Nycaloths are now Mezzodemons and Nycademons.(The Mezzodemon is in the 4th Edition Monster Manual.)
-There is some speculation that these beings form a particular strain of Demonkind, servitors of a yet-to-be-named Demon Prince,and that they have more nuanced goals than most of their kin. One thing thats clear is that they're surprisingly willing to work with mortals-Mezzodemons have been sighted patrolling the streets of the great Drow metropolis Erelhei-Cinlu. they still have a mercenary streak that is uncommon among other denizens of the Abyss, who are usually content with destruction for its own sake. Perhaps as a result, they're more disciplined than most Demons, more able to coordinate their attacks, and more likely to be soldiers than brutes.
-THIS IS AN INTENTIONAL STEP BACKWARD TO THE ORIGINS OF THESE CREATURES, FIRST INTRODUCED BACK IN 1978 IN THE VAULT OF THE DROW ADVENTURE. Their names were always pronounced as if they were Demons, and they had close ties to the Drow from the first. In the absence of a NEUTRAL EVIL PLANE IN THE NEW COSMOLOGY,folding Yugoloths in with Demons or Devils seemed the LOGICAL SOLUTION. Their nature is more Demonic than Devilsh, and so they ended up in the Abyss-though they are perhaps the most Devil-like of the Demons.[/SBLOCK]
