One after the other, the impurities reached Tista's green core, forcing their way in. The mana reacted strongly to the invasion, giving its all to wipe out the foreign objects.
Lith could watch via Invigoration a small scale war of matter versus energy taking place inside Tista's body. The green core slowly turned black as more and more impurities amassed inside.
The pain grew as Tista's core darkened, until Tista couldn't bear it any more and screamed at the top of her lungs. Lith knew the pain was normal, so he kept watching. It had happened to him multiple times.
Tista's mana core started to pulse, contracting and expanding like it was going to blow. Then it released a powerful wave of cyan mana that purged the impurities inside and outside itself.
