They ended up talking until a very late hour and by the time they got back to their room all everyone wanted to do was to sleep.
Fortunately they didn't really need to do anything tomorrow, so they could sleep for as long as they wanted – and yet Calen woke up with the rising sun anyway.
When they were at the second temple with Tharion he told himself that he woke up early due to the unusually short memory snippet, but now he realised it wasn't true.
It was his body, it was starting to need less and less sleep; whether it was a result of becoming a spirit or the body enhancing elixirs, rest was slowly becoming an optional luxury rather than a necessity.
He was fairly certain he could easily stay awake for several days without any negative consequences. Others might see this as a boon, but he hoped that he would retain the ability to sleep even when he wouldn't technically need to.
Eternity would be even longer if he had to experience all of it.
