Because Morpheus needs someone to "record" adventures and new sights (which is why he placed the item in the MC's territory and had blessed it in the past) he shouldn't bless it or similar to Adrian. He must know that he gets involved in numerous situations and makes several trips (due to his race and titles) Regarding distrust, since Adrian is the Arbiter of the Underworld, there is a Soulbound blessed by his older brother (I imagine he must have felt) being his father and aunt's champion. Not to mention the possibility that his mother and Thanatos talked about him, doesn't that make the MC the perfect candidate to at least receive a blessing? I think it would be interesting... maybe a blessing that would improve his Evil Eyes or just his mental power or something like that…💭💭
