Here, have some fanart of Riven, sequel to Myst.

At some point you end up in an underwater lab with a big viewing window. If you press the right button, you summon this creature, who will swim by and stare at you. The people of Riven seem to revere the Wahrk as some kind of deity. Or perhaps they just pay it extra respect so that they don't end up as its lunch...

Watercolor practice. I feel like I am getting the hang of them! I still use too much paint and have to wait forever for it to dry before I can do another layer, but I'm getting better at it anyway ~
