From a low hillock in a vast plain, the entrance to the Noil Ruins is as unobtrusive as it is a gateway to wonder…
The Pelezians, or “clay people” were strongly bound to the earth. In fertile plains and valleys they lived their happy existence, peaceful, yet ever on their guard. Many nomadic attackers they defeated, until a different enemy came; their advanced technology and weapons (and magic) were beyond the skills of defenders. One-by-one their settlements fell, until the clay people were not more.
To the greedy students of the past, their heritage is but not forgotten.
Magic is like alcohol, the more that is used, the more it causes a hangover later on and the less judgement one has when using it. If one waits a while after casting a spell, things "detoxify." A cantrip or two is like a sip of weak beer, whilst a large creation spell is like a bottle of vodka. Cast something too big and you can die from magic intoxication.
