Consumed by the Blue Azologoth. (Patreon)

The contractor sent two fresh young sublets down to the lower levels of her facility to test the case & its contents next to her "pet" azologoth. 

The Blue type Azologoth is something never seen before, possibility of it passing near electrical infrastructure turning the water in it blue. 

The sublets care not for the details, they only care that they dont get consumed.
