For May 2021 we had the Songs, Tales and Legends Challenge. Here are the creations.
The results were
Bardic Instruments random tables
Axes of the Bards are four d20 tables for mystifying musical marvels.
I got a miniature brass ocarina which emits a faint glow....
Sorcerous Songs at Donjon
Over at Donjon is the "Weird Random Generator" of Sorcerous Songs with a cthulu horror twist. Options of 1890's Victorian England, 1920's New England and the modern era.
"You hear an eerie variation of Prince's "Purple Rain" on the radio. If you listen to the song, make a Sanity roll. If you fail this roll, you are momentarily confused about where the second moon has gone."
Music in the Cultures
Iron Arachne added Music to the Cultures Generator.
An example is
"This style of music has a single rhythm with a slow beat. It is very loud, with simple harmony. It has a simple melody with a low pitch in a minor key. Usually, it has a resonant timbre."
Over at Chartopia there are many random charts.
Songs, Tales and Legends Collection is a list of random charts fitting the theme. Including the Random Bard Table
Dungeon History at Chaos Gen
My entry was a Dungeon History generator giving an origin story and recent events for a fantasy dungeon.
An example is
his dungeon was created by demonic adventurers. It is an elemental fortress and it has a twin in another realm. It is known as Darkhelm Manor and recently a festival is being held here by a local temple"
