So, the Mage's Guild has agreed on some basic aspects of magic, and we have some jobs for you. First and foremost, you need to find someplace(s) to place a magical biome -- a region permeated with a surplus of magic and home to many strange creatures. We haven't decided on themes for magical biomes (good, evil, etc.) so we're leaving it up to you for now, so long as it supports the quest I'm gonna mention later. Second, you need to design a Yellow Mana Elemental, which is going to spawn in the magical biome. It shouldn't be too hard to kill; basically any schmuck who knows what he's doing and has a weapon and preferably a shield of some sort can kill it no problem. Make it so that a character would be able to harvest the following from its corpse: 1 yellow mana crystal, 5 units of astral dust, and a 25% chance of an elemental shell. We'll think of more magical creatures later, including other types of mana elementals, but this is the most urgent thing because there is a quest we want to use that requires them to be present. The quest is simply to trek into the magical biome and kill a yellow elemental, harvest materials from its corpse, then bring them back. Cost and reward are up to you. Just keep in mind that this is supposed to be an entry-level magic quest and that the player will probably have to spend 3 gold anyway on a sword and shield, so try not to make it too inaccessible.
