So, time to come up with a proper plan now that they had all this new information to work with as well as Alvin's insight. To start it off the both of them took another look around to make sure no one else was spying on them. What they were preparing to do might cause a bit of panic even though the both simply relaxed and the demon reverted to her original form, horns and all. "Okay. First, we need to be able to approach the gate without immediately drawing suspicion. One of us will need to look like we have an actual purpose in being there... And that shall be me." At that the human started concentrating. Her threads extended out to pull in some power, and as they returned they started weaving throughout different parts of her body. With each passing moment they started to take effect, her eyes shifting and slanting while a pair of spectral wings started forming from her back before they stretched out and started to solidify. Her cheeks rose higher, her features themselves becoming sharper in a way that made her look like a different person that was distantly related to Prudence. By the time she was finished the wings themselves would spread slightly, the pure white nearly radiant as they glowed with power while her hair and eyes seemed to reflect that shine and looked nearly golden in the light. "I'll lead us in with this disguise, and once we've actually crossed the threshold into Heaven I can absorb some of its latent energy to strengthen the deception. I'm going to need it since these wings aren't exactly real." That much Alvin would be able to see since he saw how they were constructed. They were an illusion, albeit powerful and made all the more convincing by Prudence sacrificing a great deal of power to give them actual substance instead of being nothing more than empty shells. She could even feel them weighing down her back, the threads themselves built off of her own frame and giving them a proper anchor to twitch and shift as she stretched herself out to see just how well they could actually work.
"Since I can't exactly pass myself off as anything other than human thanks to the symbol I'll need to enter as one." Thus it was time for Pru to transform. Hers was much smoother and fluid, her body instantly reacting to her desires as her demonic features simply shrank and were absorbed by her body leaving her looking much like her twin had only a few moments earlier. Beyond that she did nothing to change her actual beauty, her features staying just as lovely as she usually did while the holy symbol was activated and concealed her true essence even while her threads didn't shift in the slightest. "Prudence will be an angel returning with a possible recruit to add to Heaven's ranks, and I shall be her acolyte set to serve her in whatever way she sees fit. We'll still look alike, but since she looks different we can play it off as possible members of a family line, something like a human lineage descending from some faithful followers that had been 'blessed' by her and now strove to repay that dept through dedication and duty." A moment was taken to think that through. "That doesn't sound too outlandish, right?"
Whether Alvin answered one way or another they could adjust, and they continued to include the most important part of this deception. "You shall be the candidate we bring to Heaven. I discovered you as you were being tempted by some mermaids, and though you were tempted you held to your faith and struck them down as they started becoming a little more aggressive. It's not exactly in character for the average mermaid, but if they fall under too much influence of the curse it can cause them to act out at times. The fact that you withstood their wiles showed great character even if you were receptive, that should let you react to any flirtation from either us or the other angels without seeming suspicious, and because of that I offered you the chance to become a Hero under my tutelage. I'm still going to try and keep myself from attracting any attention, but if any of the angels start showing any interest I may just end up jumping behind you and say something like I'm impure because a monster managed to attack me with their lecherous ways. It explains why she's so sexy even while trying to hide, and it gives us a reason to try and find Naznia. Since she made that nasty flame maybe she has a way to use it to purge a human soul without going all fire and brimstone and possibly killing the human that's infected. How's that sound?"
