The next day, Shuule woke up in the pitch black of the top floor with a shiver. She rarely actually got cold, again because of her shifting abilities, but not only was Set like sleeping on an ice block, she became aware that now, he had become rigid. It was almost like the hibernating mass of coils was actively sucking heat away from her.
She jolted, and would have burst into her fox if she wasn't already in it. She knew what hibernation was. The two of them had talked about it extensively, away from the others, because like the Legacy, he didn't want everyone to know about it. Of course beasts had been aware for centuries that the snakes were their most vulnerable when they were asleep, but they didn't know that their heart rates and pulse slowed to the point that Shuule thought for a split second that he had indeed just died. She growled, about to panic, before noticing a faint heartbeat, that she could only detect with her superior hearing while the house was silent.
