The demigod bar is the imagined afterlife for demigods who have just ascended. After completing such a monumental feat, new demigods and demigoddesses would naturally want to put their feet up and relax with a refreshing beverage. To this end, players have been known to ascend with ice boxes filled with potions of booze (and an optional blessed greased figurine of a foocubus of choice).
While a fairly prominent piece of community "fanon", no variant or version of NetHack has featured such a bar as of yet.
- The NetHack stories by Virgo Vardja (dead link) sometimes feature the demigod bar.
