They truly wanted to call a renowned apothecary who could save Davis's life, but Davis had been given a title that connected him with Death Laws. Which renowned apothecary would be daring enough to cure him, and even if they did take up the task, who's to say that they won't secretly end his life?
At the moment, when the world thought that the Emperor of Death had died and relaxed a bit on that note, heard that he was still alive, perhaps the entire righteous world would be aggressive towards them while putting negotiations and reasons out of the table.
No matter how they all thought, bringing outsiders here was dangerous, and the end result of Davis recovering wasn't even promised to them, making it so that it was too risky of a decision.
