You missed a zero there, it was an army of 1500 made up of Lv. 100 players and NPC mercenaries that they hired who were likely slightly weaker. Don't know the exact ratio of player to NPC but seems rather irrelevant since that’s a force this world would probably need their entire population to rival let alone surpass. However, this only means that assaulting Nazarak itself is suicidal, if PDL is able to draw a couple of the floor guardians or Ainz out into an ambush he could prove to be a worthy challenge.
