Yeah, so who died?

So yeah, who died? -- I ventured into the Mighty Trees area Tuesday and came across this grave. I'm not sure who this represents, but rest in peace indeed. Obviously the creator the grave had someone in mind they were reflecting on and came up with this memorial inside Planet of Cubes. What do you think? Have you ever done this? It's a different take in grieving the loss of a loved one indeed - But if gaming and real life mirror one another, what of it? Rest in peace.
