In a world where magic is common as air, u become the First and only Summoner.
What is a Must for a Summoner(aka:u) to have in this world?
You can choose 3 basic powers (not Omni, meta, absolute, omnipotent, and night-Omni). of course, u already begin with Summoning!
(u can choose in what Era/type of world u live but by essence, the world will be always "Magical")
