Lind had been angry but seeing his mother nearly lose her hand cooled his mind. She had to cultivate after that and he realized she was still consolidating her foundation! She had only been a Radiant Tier for no more than 3 years at most.
She also had zero weaving ability. She was an alchemist down to her core.
He had many questions that he slowly organized as he paced around the now cramped cavern. It was never meant to be more than a safe haven from the storm for just him.
The flames made by the weavings were fine but the space was a bit tight for 2 people. He checked the sigils but nothing was changed. Everything was working normally, plus he had entered without an issue so what was wrong?
He let his Eyes follow the sigils and traces only he could see. Even other Maesters would only be able to perceive with their aura a weaving they had created but his Eyes let him see it directly.
