Welcome matmaisan! Since your character will use divine magic, I should mention a bit about the religion of the world.
Myths tell of Elder Gods that created the world, but they left long ago and very few revere them or even remember. Today people worship the New Gods, more akin to angels and nature spirits in other settings. They hold very specific titles and portfolios, and they might only hold sway in certain regions of the world. Some of them are mortals that ascended to godhood, others are concepts given life by worshippers. Although they don't age they can be killed, and all require worship or they will fade and die.
The most popular religion in Iskandar is the
Church of Lothian. It is based around a martyred saint named Lothian who rose from his own grave and ascended into Heaven, becoming the most powerful of the gods according to his followers. In fact, the harshest of Lothian doctrines maintains that Lothian discovered that all other beings claiming to be gods were actually demons in disguise; this belief teaches that he rose again to bring order to the previously disordered, godless universe. This was the state religion of the Vendian Empire, which has endured after the Empire's collapse twenty years ago.
I won't list all the New Gods you might worship as there thousands. Here are some related to magic:
God | Alignment | Portfolio(s) | Description
|
Kharos, God of Magic | Neutral | Knowledge | An old deity, Kharos is lord of wizardly magic.
|
Locharit, the Goddess of the Written Word | Lawful good | Knowledge | A religion of wizards and scholars, also favored by gnomes.
|
Niveral, God of Secrets | Neutral | Future, Knowledge | Also known as the Master of the Five Lost Lores Niveral is a minor god worshipped only by those who seek forgotten secrets and knowledge no longer known. |
Also feel free to define your own god. There might be multiple gods of magic and wizardry with different, competing followings.
