"I can't believe they forbade me from visiting this 'underworld'. Those old bastards underestimate me, I'm a sacred angel for heavens sake." Lucifer vented as he descended the stairs, he transformed back into his more human like form. Although everyone in heaven was an Angel, not many has seen the full angelic form of a tier 7 since they were so rare and although he liked attention, he had more fun things to do.
"Well, at the very least they didn't for I'd me from interrogating the creature. I wonder if my friends would want to come along." Lucifer said joyously and instantly activated his [Advanced Telepathy] skill.
[Hey guys, let's meet up, I have something to talk about.] Lucifer said in the telepathic group he formed with his friends. A telepathic group was basically a group of individuals with the [Telepathy] or [Advanced Telepathy] linked mentally. You can send a message to all the persons in the group which is easier than sending it to them individually, although, the people in the group can choose to ignore the messages.
[What do you want to talk about Lucy?] Luciel's voice sounded in Lucifer's head
[Yeah what could be so urgent....I'm kind of busy right now.] A deep voice sounded in his head
[Trust me, it will be worth it.] Lucifer said excitedly
[Fine, I'm at my mansion right now. You can just portal over.] The deep voice said before disappearing
[I'm still at the mountains, we can meet at Azazel's place.] Luciel said
[Ok.] Lucifer said and ended the conversation, he then created a portal to Azazel's house. As soon as the swirling golden portal appeared, he stepped through and appeared on a grassy plain over a hundred kilometer from the Celeste but even so, he could still see the celestial castle. He turned around and looked at the building standing in the middle of the grassy plain, in the middle of a lake, the building was a giant mansion with an expertly built bridge made of a dull yellow brick material. The mansion didn't look that large but Lucifer knew better than to underestimate it's size, the mansion was pristine white in colour with the edges painted red and a large Crest of a shield with two spears across it in an X shape, above the large doors of the mansion.
"Let's do this." Lucifer said and took a deep breath before stepping onto the bridge. As soon as he took a step on it, he felt the space around him ripple and he nearly stumbled as entering the space domain erected around the mansion was a bit disorienting. He looked back at the mansion and walked along the bridge although he hated walking most of the time when he can just portal anywhere he wanted but he knew he had to bear with it. The space domain prevented him from using his [Portal Creation] skill while inside and he couldn't portal directly into it from the outside easier. The space domain also prevented unwanted guests from entering. This was done because Azazel and his family preferred their privacy, and having a bunch of Angels who can just go in and out as they pleased just didn't suit them.
'Even if it's inconvenient, I have to say it's quite ingenious.' Lucifer thought as he walked across the bridge. A domain like this isn't something that just anyone can create, or atleast one so stable and permanent. Creating a domain linked to your affinity was an ability that you gained at tier 5, it basically allowed you to use your Affinity at a much wider scale than before but these domains drained your energy fast and you can't keep them active for long. And if Lucifer remembered correcfly, this space domain was done using a [Holy Core], an artificial [Angelic Core]. They managed then, somehow, managed to inscribe a rune into the [Holy Core], giving it the ability to use a domain. And since the [Holy Core] functioned like an [Angelic Core], it absorbed the holy energy in the vicinity, giving the space domain an unlimited source of energy.
