"What would Scalpel be looking for"

Well my thoughts on the matter regard my headcanon of magic in this and follow a very similar route to the one I used in resurrecting Scalpels "Risen". Basically my theory is that magic works like a network of veins across the world, with a vast connection of small capillaries providing magical base line magical output for all ponykind, and larger arteries consisting of the main streams which transport the vital magical energy and distribute it to the smaller vessels. My theory revolves around redirecting some of these "arteries" into one position, making a certain point of the planet have an immense amount of latent magical energy run through it, and then "ripping open" these "arteries" so that the magic bleeds into Mundus. What Scalpel would be looking for is three things, 1) a way of redirecting strong streams of magic to one select position and saturating the area with ambient magic 2) A tool to literally rip open these "arteries" - Scalpel is not strong enough to do it himself being only a mortal, thus the reliance on the Alicorn horn +machinery- and special tools for the delicate process of doing it without the raw energy causing a massive explosion and killing him 3) a spell similar to that of Tirek's amulet which harvests magical energy and infuses the very essence of the person it is cast upon with huge amounts of raw power.

"and what do you want from the entry?"

Don't know quite what you mean, perhaps a bit of back and forth, talk about all the crazy shit stirring up in the world now we have fourth Tier alicorns running about, perhaps an deal being made between the two- in essence "you give me your forbidden secrets and I'll share mine" sort of thing. If you want to, you could have your guy tap on the door and Scalpel be all grouchy and yell for you to come in, only for you to be greeted by him working on a lot of corpses with a lot of machinery attached to them. :P
