Rex spent the rest of the day resting.
He allowed his body and mind to heal before he moved again.
Since his regeneration was helped by the Restora Patch, his body was fully healed before Kaelthar came back, which was perfect. He could now move his body again without a problem, but his mind was still heavy, cloudy—still not properly recovered from the Voidal Monarch's attack.
Fortunately, Kaelthar delivered what he promised.
As basically an important young master in Sky City, Kaelthar has some loyal followers, with one being his capable servant, Erwin. Though he wasn't as strong as most servants, his connection was incredible, allowing him to get things done with relative ease.
He was friends with a lot of servants and even some royal knights.
Due to that, he was able to locate Devo.
Of course, Erwin didn't come down—Kaelthar relayed the message from him.
