A long time ago, only dragons lived in the ice mountains of the far north. But humans tried to settle in the inhospitable lands. They struggled to survive in the wilderness, losing many of their number, and so the Moonscale flight took on human forms to help them. This fostered a friendly relationship between the dragons and the humans, spurring them to reveal their true forms and cast a protective veil over the mountains. By combining their magical power, the Moonscales shielded the humans that they favored from the bitterest colds.
The civilization flourished at first, but as history wore on, it began to fade, and then rot. Powers outside of human ken began to worm their way in. The humans began to worship one of these Old Ones, and they built a temple in the face of the tallest mountain dedicated to one named the Ever-Burning Vengeance. A vestige of the Old One was almost brought into the Material Plane, and the dragons had to combine their power to seal it away at the cost of the civilization that summoned it.
The Moonscales, then, must guard the temple and keep the fragment sealed away. Through the ages, the Old One will gather enough power to threaten the safety of the plane, and one of the dragons will give their life in the fight to seal it back away. Thus, Celever only has a sister remaining, named Argenta. Their older brother, Curufin, sacrificed himself in the event that called Celever back to his home, where a group had broken into the temple and accessed the rift to the Far Realms within.
Towards the end of Celever’s story, the two notice a caravan of people under attack by a strange creature and a mage setting fire to the wagons. Sai drops down on the chimera from above. While Celever flies away and comes back to fight in human form, Sai fights the mage and the creature, taking several hits in the process. The chimera sets the caravan on fire, prompting Sai to hold the mage and demand he call off his creature, threatening him with poison if he does not comply. He teleports away, but after the chimera is vanquished, Sai pins the wizard down and pours the poison into his mouth. The wizard dies swiftly soon after.
Meanwhile, Quarion lead Sirya, Ulfric, and Malcer to the purified spring in the Golden Wood. There, they discovered the dead body of Sariel, the druid who mentored Quarion who was in charge of purifying the spring against the swamp. Surrounding her body were multiple red-capped, small fey, who the party quickly defeated.
Once the battle concludes, Quarion casts an involved spell for some time, bringing Sariel back in a new body. She returns and confers with Quarion about the happenings surrounding her death and the encroachment of the Siren’s Bog into the forest. She was killed by a group led by a changeling, who seems to be an agent of the Lord Under the Bog. They decide they need to track down this agent before continuing further.
Using the spring to scry him, they discover that the changeling and his crew are disguised as emissaries from the Silf River in the court of the Lady of the Wood. The party decides that they will root out these infiltrators to prevent them from accomplishing whatever goals they may have. The next morning, they set out towards the court with Quarion.
