Void Janitor

A few days passed just like that, while Warden mostly spent it on the labour of cleaning duty and guarding… After the recent attack on the mines, the higher-ups had been quite tight with their security.

So, by the morning, Warden would clean toilets and camp, and after that throughout the day, he'd stand guard around mines. Other than a few cursed creatures, there had been no attack.

Thankfully, the boring task provided him with the serene environment he needed to work on his rune smithing. So, after working every night carving the runes, Warden was almost two-thirds done with the orders. He certainly hadn't thought he would be this free… 

"Ahaha, void energy destroys 99.9% germs with just one splash," Warden laughed, pouring a half bucket full of void energy-infused cleanser into the toilet. 

As the water was splashed away, what was left was pristine white tiles with no sign of abhorrent crap.
