The group was massive. It was as though they had gathered all of their forces, or at least a significant number, and placed them in this single location in preparation for Gus to have come that way.
The outside walls of the arena had been converted into something akin to a fortress, reinforced with defences. Turrets pointed outwards, and were manned by the small Bloody Dawn aliens that Gus had seen beneath the temple. The four legged tanks were hooked onto the walls, and they too acted like turrets.
In front of the arena was where the main bulk of the force stood. Lines of Shenia were placed before tightly formed groups of Bru'uka, with the Vanguard Commander in the very front. He was joined by a couple of other Shenia that were outfitted in the armour of the Nightblades.
