That said, the next reward was a purple and blue crystal of darkness and shadow that merged with blake's body, it's information entering Blake consciousness upon merging: A Shadow Space Shard, which held an isolated area of the Shadow Realm inside that was separated from the Shadow Realm before the Sealing. It was its own smaller realm that'll grow with Blake as he did. Eventually, one day, he may be able to merge it back with the Shadow Realm. He can enter this space anytime and store things inside it.
The last object was a small tennis-sized sphere as black as obsidian with a slightly purple hue glow to it. Upon touching it, the info it sent into Blake's mind was so shocking, it made him grasp.
It was one of the three ingredients needed to unseal the Shadow Realm — It was the battery core of the Shadow Realm.
