The Temple of the Diamond Dragon stands upon the peak of a mountain, lost amongst the clouds for 5 months of the Year. The monks that inhabited the temple used to teach the Way of the Dragon Soul, a technique that imbued the practitioner with the might, intellect, and durability of the diamond Dragons.
They only took the very best and most capable of people in as students, until one day they closed the gates and refused to take any new students. The Grand master had died and the remaining masters couldn’t decide on who should become the new Grandmaster.
No one knows what happened, but those heavy wooden gates never reopened again, until now.
The House of Ice was home to an evil sorcerer that drew her power from the Frostfell and built at the very edge of a promontory. The sorceress was run out of the building by a group of adventurers, opening a portal to the Forstfell to escape, and encasing the building in sheets of ice, frost, and snow.
Recently the entrance to the house of Ice has started to thaw, enabling egress to the house for the first time in centuries.
The house of eternal night is an old cult that worship the formless nameless beings of the negative planes. They shroud themselves in shadows and illusion. For years they sacrificed countless innocents to the dark powers they revered.
They built the House of Eternal Night on the edges of a large swampy area, full of reptiles and other carrion creatures that would help clean up after their rituals.
When it was created, the House was a marge large edifice than currently sits above the murky waters of the swamp, which over time has claimed the majority structure and its cult inhabitants.
The Den of the Jade Knight was originally an old Dwarven waystation. It was built as part of an underground network of underground roads and cartways. It was abandoned by its dwarven creators after a disastrous battle with Dark Elves from the surrounding underworld.
Over time the surface world forgot the existence of the waystation until The Jade Knight discovered a secret entrance when the floor of a tomb that had been built on top of it collapsed. The Jade Knight now uses the Waystation as his base of operations.
