So, he does the obvious thing. He outsources. He's not the only mage in the world, not even close, and he just so happens to be extremely rich. He asks (well, asks and then pays) a talented stoneshaper to make the necklaces in one fell swoop, and then spends several hours bugging significantly less busy mage healers at hospitals to make the portals. He only manages to get three sets, but he deems this 'better than nothing.' Especially considering most mages don't have a strong enough bloodline to manage a portal on their own. Just three was difficult to get, and required a lot of teamwork.
With that done, he heads off to Perinixu's temple, to shower Spring with gifts. In the sense that he will hand them to her, and then ask her nicely to use them to heal people.
"You get a prize. Congrats. Now! You!" She points at Prime. "You did this, didn't you!"
"Oh, fuck you, you know exactly what I'm talking about." She motions around them, to the temple. "This shit! This fucking shit! What the fuck is this?!"
"You let her in," she says, in a deadpan. She looks at Prime. "What. The fuck. Other planes?! Really?!"
"Okay, take your fucking smarmy attitude and shove it up your ass, you hypocrite, I don't believe you, you asshole!"
"He didn't - some friends of mine came to visit him and later introduced us," summarizes Aya. "That's all."
"Yes, we're both bastards, that is the thing that happens when we're born out of wedlock."
"Because your testicles never dropped and you're a manipulative, traitorous asshole?"
Prime sighs. "No, because the last time we spoke you were shouting at me. Sort of similar to another thing that I remember, hmm, the example escapes me. Something involving jumping straight to namecalling before I can even explain myself. I don't quite know, there are so many examples, it's hard to narrow it down to just one."
Aya doesn't have any positive contribution to make here. She goes back to writing up how she wants the wording on the sign explaining how offerings work, watching the twins warily.
