Sage is an entity made of anti-matter (Yes, the same stuff EXEs are usually made of lmao). Instead of being a bum hedgehog with bleeding eyes and saying "I am God" and allat, bro decided he was just gonna be laid-back smoker who really didn't care what happens in life, as long as nothing bad happened to him. Around his second or third year of existing in the Mars-Verse (Or whatever it's called) he finally met Mars/Brownie and Vivian. Now (Like idk how many years later, just not that much) he's lowkey chilling with Vivian and allat now. Oh and he's constantly rage baited by Blocky
