Brasske

Name: Actual name is long forgotten to time, but the rough translation was 'Brass Dragon of the Final Lake', shortened to 'Brasske' over the eons.

A great magical construct, created to house the last of a magic spring long sought after, and abused by those seeking it's powers. He is tasked with keeping the last of it's water safe from those that wish to misuse the power it holds. While the original location and those that protected it have long since passed away generations ago, Brasske wanders lonely spaces to avoid contact with large groups of humans, never staying in one place too long.

Brasske is completely harmless to those that pose no threat to his cargo, and is often known to enjoy a child like interest in smaller creatures, interacting playfully or even protecting those that are in danger. His speech is kept to simple words and comes out in tones of running water and metal bangs. The lake contained in his glass belly have gone wild over time, and can provide varied and unpredictable effects. What is static is that any creature in that space can still breath normally underwater, and any wounds are healed, everything else is up to random shifts in magic.
