While Michelle and Alexander were in the basement beneath the tavern, looking for the source of the intense humidity, Kieran, Anastasia, and Ivona were in the jungle, fighting a few huge snakes relentlessly attacking them.
They were already spent, both physically and mentally, because the snakes attacked them early in the evening and didn't give them a chance to rest throughout the whole night. If they soon didn't come up with a way to deal with them, they would end up in real trouble.
But the snakes didn't even give them time to think properly.
Kieran and Anastasia were defending against the attacks while Ivona pumped them with her light element spirit energy to help restore their energy and give them some kind of boost, but she was already exhausted. And as she also had to dodge the attacks of the snakes, her control over her spirit energy was slipping, and the support she could provide got smaller.
