Tymora

“Tymora (Lady Luck, Our Smiling Lady) is the bright-faced goddess of fortune, the one to whom gamblers and game-players pray in Faerûn. Our Smiling Lady is said to love none so much as those who gamble with the utmost skill and daring. Yet she is thought to watch over all who take risks to better their fortunes.

“The battle cry of the followers of Tymora is ‘Fortune favors the bold.’ Someone might say words to Tymora before any endeavor in which a little good luck would help, but not when an incidence of bad luck might occur. (On such occasions folk pray to Beshaba to spare them from bad luck; praying to both is thought to anger both goddesses.) One common method of divining the future is to toss a coin to a stranger (typically a beggar) and ask if it's heads. If it is, the coin is left with the stranger as payment for Tymora’s favor. If it's not, the stranger can choose to keep it (and the bad luck) or return it.

“Those who favor Tymora - as distinct from folk who invoke her name by mumbling over the dice - tend to be daring sorts. Adventurers and gamblers make up much of their ranks. They all have the belief that what is good about their lives is the result of having both good luck and the bravery to seek it out. Tymora has worshipers among all sorts of folk: the dashing young noble, the risk-taking merchant, the daydreaming field hand, and the scheming ne'er-do-well.

“Priests of Tymora and temples devoted to Lady Luck are scarce, since her faith tends not to stress a need for intermediaries: ‘Let the lucky man and the Smiling Lady suss it out,’ as the old saying goes. Shrines to Tymora at gambling parlors aren't unusual, however, and sometimes such establishments attract a priest and effectively become temples.”

The Legend of Tyche and Her Twin Daughters
“Before the Dawn Cataclysm, there was but one goddess of luck, Tyche. Ever flirting with fortune and disaster, Lady Luck bestowed and withdrew her favor at a whim. When her current paramour, Lathander, started a fight among the gods, Tyche kissed the Morninglord with misfortune and wandered off to explore the world.

“During her travels, Lady Luck discovered a budding rose of unequaled beauty. Delighted with this fortuitous happenstance, Tyche reached to pluck this delightful token, which she assumed was a peace overture from Lathander, who sought to regain her good graces. Much to her amazement, Lady Luck couldn't pluck the rose from its bush no matter how hard she tried. Frustrated, she cursed the rose with bad luck, and the flower’s stem broke in her hands. Tyche put the plucked rose behind her ear and continued on her way. Unknown to Tyche, the rose was a manifestation of Moander, god of corruption and decay. The severed rose stem crept into Tyche’s ear and subtly began to rot her from the inside out.

“When Tyche returned home, she came across her dear friend, the goddess Selûne, waiting to speak with her. Also waiting for her were Lathander, who wished to regain her affections, and Azuth, who had come to mediate the dispute between the two. Selûne wept great tears as she saw the corruption destroying her friend from within, and before Tyche could discern her intent, Selûne lashed out with a bolt of purifying light. Tyche’s rotted core split down the middle and a smaller, brighter version of the goddess of luck stepped out, allowing the goddess of the moon to save that which was good and pure in her friend. However, following this first figure out of the rotten shell was another form stunning to behold, but full of dark malice and capricious ill will. As the two forms emerged, they immediately fell upon each other in hate, struggling madly, and were separated only by the combined efforts of all three visitors.

“It is said that Tymora, Tyche’s Fair-Haired Daughter, embodies all the grace and kindness of her mother, while Beshaba, Tyche’s Unpleasant Daughter, got only her looks. Since their birth, the twin aspects of Tyche - Tymora, Lady Luck, and Beshaba, Maid of Misfortune - have battled each other, contesting matters as great as the fate of nations and as small as the flip of a coin.”

Background
Forgotten Realms’ co-creator Jeff Grubb remembers early creations of their gods: “I checked with one of our editors who was wiccan if any of the gods would raise hackles from people who might worship them. The only one she tagged was Tyche, which I turned into Tymora but otherwise left intact. However, I did not remember the map tags, so the original project went out with Temples to Tyche marked on them. Later we would retcon them with Tyche being a Luck goddess separated into good luck (Tymora) and bad luck (Beshaba).”

Appearance
“Lady Luck sometimes appears as a silver bird or as a silver pegasus. Her avatar is a slim, almost boyish maiden with silver hair and eyes like blue-black stars. Her features are breathtakingly beautiful, and her movements are always dexterous and graceful. Tymora can change between bird and human form at will.”
