Rainbow Waterfall Forest[]
From Lore Master: HEAT
"There are places in the Solverse that can only be given justice when seen in person. The painted soil of Cellaphar XI, the Emerald Temples of [REDACTED], and the Underwater Continent of Mavis III. Add to that list the Waterfalls of Heaven’s Border World. Not only does the planet sit near the event horizon of a massive black hole, the effects of gravity are unpredictable on the one hand, but can also become spectacular and beautiful on the other. Color is especially vulnerable to local changes in the visible spectrum, which is why the waterfalls of the planet are often confused with rainbows. Swimming in the mixture is encouraged by locals, who know their planet has fewer days ahead than behind."
