The Empire had a naturally spawned one from Kattze. Which means that at one time or another there may have been another.

The Empire branch of the Adventurer's Guild is probably aware of them... considering that Fluder and his Disciples had one locked up over there and the Imperial Army definitely knew about it seeing as they got thier butts kicked by that single one before Fluder stepped in. And apparently some of the Adventurers and Workers over in the Empire may or may not have been his Students at one time or another. (Arche...)

It's entirely debatable if the information would make it between the two separate branches or not. I would assume not since the Empire seemed to have been treating the one Death Knight as a low-priority State Secret or something similar.

And no, he's not the only Necromancer. He's probably the highest level one and the only one capable of summoning the Lv80+ ones... but not the Death Knights. Technically speaking, the Redcaps that Lupu summoned using the scroll from the library (which was a Yggdrasil scroll, not a NW material one) were higher level than the normal Death Knights. (They're estimated to be mid Lv20ish, but with defense pushing Lv40ish. Ainz summoning them would probably boost this quite a bit. The Redcaps were Lv43 or so straight out, using only the scroll - so Lv43 is the *lowest* they can be, and she got multiple Redcaps off of that scroll.) My guess would be that the Death Knights, Zombies, and Skeletons (The Zombies and Skeletons were used against the Lizardmen, the Death Knight Army was not yet available or still being summoned as Nazarick didn't use them for the Lizardmen... they instead used the Guild-spawned House Troops, which are much better equipped than the Death Knights; the House Troops did not have mounts but did have full sets of magical equipment, were all Foot Troops, and numbering into the 5-6k range.) would be the supposed scroll material and/or NW money tests the Head Librarian was conducting for Demiurge and Ainz, which would explain why there were so many of them since each cast only summons 1, for the Death Knights anyways. Waste not, want not... and would make sense since it would be more efficient to combine the tests and troop building into one.

Actually, the way the Guild Defenses were described. Any of the Floor or Area Guardians may be able to summon low to mid tier mobs such as the Death Knights using the Defense Systems so long as they had the gold to feed to it.
