Glad to see this finally getting some interest :). 

@rush99999: I like your character already. A codex is simply a book where your arcane knowledge is stored. The complexity and vastness of arcane power is impossible to remember so a written record is a must. It would be unwise to lose your codex, as they are tied directly to your power. Some sorcerers have constructed vaults to store these prized possessions.
