J'ryn'zalas is one of many military fortresses in the city of Tu'narath. The supreme commander of J'ryn'zalas, a githyanki blackguard named Zetch'r'r, believes that Vlaakith the Lich-Queen has lost the vision set forth by Gith and is sacrificing her own people to fulfill her own mad schemes. She devours the life essences of her strongest defenders. She breeds half-dragon githyanki in a foolish attempt to improve upon perfection. No longer are the githyanki feared throughout the planes. Conquest has been usurped by complacency. All of this troubles Zetch'r'r deeply; however, his rhetoric has done little to turn other supreme commanders against Vlaakith.
Zetch'r'r seeks to reignite the githyanki passion for conquest and imagines lead a bold new regime to victory over his most hated enemies, the mind flayers. He also seeks to reunite the githyanki and githzerai as one people under his august rulership, for only together can the gith annihilate their ancient enemies. To this end, he has joined forces with the Sha'sal Khou, a faction of allied githyanki and githzerai, and takes strides to protect its members.
The bastion of J'ryn'zalas is a three-story edifice adorned with sneering gargoyles and glowering bas-reliefs that scream or yell loudly when an invisible enemy comes within 20 feet of the walls. The noise automatically alerts the bastion's denizens.
Zetch'r'r, his red dragon advisor and steed Vrax, four githyanki knights (elite guards), and 20 gish occupy the fortress proper. Encircling the bastion are six smaller buildings that serve as barracks and training halls for the bulk of Zetch'r'r's troops: 200 githwarriors and 100 githyanki soldiers. Leading these githyanki soldiers are 20 sarths and 2 kith'raks. Stabled nearby are five juvenile red dragons (one for the bastion's kith'rak and the remainder for Zetch'r'r's knights).
Only Vrax, Zetch'r'r's knights, and the gish know that Zetch'r'r is allied with the Sha'sal Khou. Most of the other githyanki of J'ryn'zalas would be appalled and disgraced to learn that their supreme commander is allied with a faction that includes and tolerates githzerai members.

The Bastion of J'ryn'zalas has ceilings 20 feet high and its halls and rooms are unlit unless otherwise noted. The entrance is a large, curved double-door made of wood and astral driftmetal, adorned with the skulls and bones of illithids. Burned into the wood on the doors is the J'ryn'zalas Crest (a black raven perched on a stylized illithid skull).
