Crucksha are considered to mature at the same rate as humans from the moment they're broken free from the earth. So, while being made of ancient energy, they develop true sapience when given a form of their own. 

After 20 years in their sapient form, they're considered adult. The energy inside them only wanes with enough damage sustained to the body, which makes a Crucksha left alone and regularly upkept functionally immortal.

Crucksha vary wildly in their appearances dependent upon how they were formed. Typical humanoid Crucksha are larger than the average human.

You play a medium character, between 4 and 8 feet. 

Your base walking speed is 25 feet
