Since Element 115 is a substance that actually appears in the CoD Zombies mode, it should have an object page. So I made one and named it Divinium (a proper name given in the story):
to avoid confusion with the other Element 115 that's apparently in Tomb Raider 3, and presumably other games. (I can request Element 115 as an alias in the sticky separately, though Marino might prefer to make Divinium the alias and rename the page. idk.)
You might argue that Element 115 should be kept and used for non-Zombies games, but the fact remains that it should be an object page. Except maybe as a catch-all concept for fake atomic elements, but they're still gonna be physical substances.
