Angel of the Deep. You awake far below the surface. It was your nature to do so, or perhaps it was a coincidence of your particular structure being close to the ocean and built on landfill rather than bedrock. It's well known that significant parts of the Silicon Valley Research campuses were built close to water on artificially created land, essentially shrinking various natural estuaries to make room for buildings on scenic ocean roads. Of course, landfill, unlike bedrock, has a fascinating property when exposed to certain types of earthquakes, known as liquefaction, which is pretty much what it sounds like: turning into a liquid. Liquids are notoriously bad at holding up multi-story buildings, leading to their swift sinking deep into the crevice created by the great earthquake a thousand years past.

Regardless, you were protected from the worst of the radiation by water that sat deep underground for many centuries. But recently, it has been drained, and you now stand on the borderline between the cave systems and the truly deep veins full of magma and the most esoteric elements that can remain stable on Earth. You also now find yourself, as you pull free, encountering a group of three humans being menaced by what might be classified as a wingless fire drake: a great lizard larger than a bus, with hardened scales and a frilled crest running from its head to its tail (you know, of course, that it is a drake and not a dragon because it only has four limbs in total, and is lacking wings). Alternately, perhaps the fire drake has found an appropriate meal, in your view. 

One of the humans is also carrying an electronic datapad, which can be read if you don't see the need for particularly swift intervention without further information.
