Tale of the Weirmaiden

Long ago, back when Jour was romping around in Belor Daeg and Sefir Daeg, a demigod named Selah was born unto Feliflón Morora, queen of Breccia. Feliflón's husband, Lord-King Malithalus, died in a battle against the encroaching sea-orcs in the Biterli coast. Left without an heir, Feliflón took her plight to the grand temple of Corellon, praying for five days and six nights. She refused to eat or drink or meditate until her prayers were answered.
After hearing her prayers, Corellon, Melora, and Sehanine decided to intervene. Corellon discussed providing a possible heir, but Sehanine offered instead, saying that her domain encompassed trysts. Melora had reason to approve since the sea-orcs were under direct orders of Gruumsh, her archrival. Corellon instructed Sehanine to approach the queen and give her a child.
That night, when praying, Sehanine appeared as an avatar and told her she would have a child to grow up and avenge her husband, and that Melora would bring about a maelstrom unseen in centuries to destroy the sea-orcs. She agreed. All but a few candles extinguished and before her stood a archetypical elf, strong and beautiful. It was Sehanine in male form, though she did not know. They made love and nine months later the queen birthed a beautiful girl whom she named Selah after the father.
Selah grew to be a keen-minded, aloof, and a lover of knowledge. She posses powers beyond her understanding and after she became an adult in society, her mother told her the truth. At first Selah was taken aback but then pensive, thoughtful about what this meant for her. Her mother told her that she was to be the savior of their people. The sea-orcs were not entirely defeated, that some survived and pledged revenge. They had been building in the far northern ocean, in hot and cold waters of unyielding pain. Soon they were to come back, but Sehanine had bestowed powers until the woman to get revenge on the sea-orc responsible for killing her husband.
The betrayal of her mother stung deep. Had she not been loved as a daughter but as a tool, a weapon to avenge someone she never met? Traitorous and selfish thoughts these were. She went to the temple of Sehanine Moonbow and prayed for favor and wisdom. A worker of Sehanine appeared, granting her wisdom to see that whichever path she chose, good would prevail. With this news, she stole herself on a pegasus to the farthest mountain of tales she had heard.
Meanwhile, the sea-orc Gurog had died and his son Grungu had risen to power. He was more formidable and wise than his father and so decided to spend the next two years turning most of his military away from Grand Biterli and east and south to the Riverlands, to force a land march across the flat Evoria and straight into the elves eastern forest, Dwennia. They would then be weeks away from conquering Breccia and holding the rest of the elves at their mercy. With almost all the elvish defenses focused on the Biterli Coast, they would prove no threat to them. And so, he sent his war galleys and menacing vessels pillaging as regular orcs to not rouse suspicion.
After arriving at the mountain just below the high cliffs of Evoria, Selah made camp on large, flat track. She prayed a prayer of favor and protection to the Good Three. Hearing her arrival, Sehanine came down as a cloud and sprinkled water upon the dry Selah. She drank deeply and fell into a powerful trance.
In her slumber she saw Sehanine smiling warmly and telling her of how well she had done in coming. She told her she was safe away from her mother and the duty she was to perform. She told her to simply dig into the mountain and reside there. She awoke from her trance with a powerful pickaxe and shovel at her feet. One strike and the ground fell ten feet. One blow of the pick and the rock carved as she saw in her mind. For a week she went on in this manner before making a wonderful and cozy home in the mountain.
But here, disaster struck. The queen was dying and used the spell message to tell Selah, who had been immune to spells on her journey, that she was dying. It was poison from the sea-orcs. her mother implored her to fulfill her duty and come back. Upon hearing this, she leapt up from her stone bed and flew through her decorative halls. Her pegasus was gone without trace.
The whole weight of the world crashed upon her. Her mother, her people were going to die because of her selfishness. She wept and wept. She wept for weeks, so much so that her chambers flooded and on top of the mountain a river flowed down into the halls. Deep fissures formed from the torrent as Selah lamented the loss of her people, for Sehanine had shown her the might of the sea-orcs. The fissures bubbled out and burst into the valley below. It flooded and soon torrents of water rushed down the many lanes of the land.
And now the sea-orc leader Grungu climbed up the rivers of the Riverlands and had just made it to the slow rivers upstream. His oarsmen rowed and rowed to push against the current. Just then he spotted a low, blue cloud rushing toward him. Intrigued he leaned out of his vessel to try and catch it while it passed. The cloud was nothing more than a large wave and it dislodged him from his vessel, drowning him moments later. The sea-orcs were driven to a panic at their leader's sudden death and chaos erupted. Wave after wave crashed into the ship, bursting them apart and carrying them back to the Riverlands and the Derelict Sea, but none survived to see the opening of the river.
Melora, Sehanine, and Corellon laughed tremendously as a purifying thunderstorm rolled upon the mountain. In the tempest Selah was comforted. She felt the gentle caress of the gods on her face and gentle kisses on her forehead. They spoke as one, saying, "You have saved your people, child, and avenged your mother's husband, the king. You have fulfilled your purpose. You may remain as the mountain, forever giving great joy to those who enter." Selah was not pleased, however. She wished to remain, but only to cry great tears so that she would remember her folly in leaving her mother.
The gods, seeing Selah's mind was made up, left her. The locals still hear wailing and moaning as if someone still cries deep in the halls and rocks of the Weirhead . That is where the name "weir" comes from, an old halfling word meaning "to cry," though now it means "farm." Everyone truly believes the Weirmaiden still weeps for her mother and that is why the Weirland gets its name.
