War Maiden Katara had fierce battles. She had nearly died more times than she could count and only by the grace of an alchemical pill was she still alive till the present.
She had witnessed peak Crystal Tiers battle. It was terrifying and not something many powers wanted to happen anywhere near them if possible. Those strong enough to keep them away still had to prepare for shockwaves from such battles.
All that said, what she had just witnessed put all previous battles to shame. The mighty emerald dragon had appeared from nowhere when a sickening blood array activated.
She had only heard of them but the lack of Qi told her it was a bloodline array. A reviled technique to use the blood of the fallen to create a powerful defensive or offensive construct.
She had never heard of one on the scale she had seen today.
