Spring 512
1st
The Great Djed Storm of 512. Many Drykas were able to get into the underground tunnel network to weather the storm, but some pavilions were not so lucky. Drykas caught above ground lost their ability to Web. The Web itself suffered massive damage and had to be repaired slowly over the next few years.
Winter 512
Throughout the season
A great plague sweeps through the city. It affects children and the elderly first, but soon begins affecting healthy adults. Most pavilions are touched in some way. Some thousands(?) are dead by the end of the season.
Summer 513
73rd-76th
Hundreds (of thousands?) of Zith launch a siege upon Endrykas as the sun sets. It lasts the whole night. They disappear in the morning, but are back the following nightfall. In total, they spend three nights attacking Endrykas from the air, slaughtering Drykas and destroying pavilions.
Late summer, early fall
Because of the massive casualties dealt by both the plague and the Zith siege, the Drykas organize a massive slaving effort to the north at the Syliran border. From the Bronze Woods and surrounding areas, the capture and enslave as many as they are able. Women and children are their targets, although the occasional man might have volunteered to join the Drykas. It is hoped that children raised by Drykas will become Drykas themselves. Women are given a bargain: if they provide a child to a Drykas pavilion, they will be set free. (I believe that, following this, Syliras cracked down on its Drykas citizens, giving them the choice of either renouncing their race or leaving the city. I'll have to look into this one, since I wasn't really paying attention to Syliras at the time.)
Fall 513
10th
The women and children that were captured are auctioned off to cover the cost of the effort and to compensate the pavilions that lost members trying to capture the slaves.
Spring 514
16th
Because of the decreased numbers of Endrykas, a large pack of glassbeaks is emboldened and attacks outlying pavilions, presumably killing several people.
Summer 514
Throughout the season
There is a massive drought all over the Sea of Grass. Since Endrykas is not near any constant water source, it eventually got so bad that clan leaders were forced to ration water. Livestock numbers took a hit during this time.
Summer 515
77th
A magical silver chest appears on the outskirts of Endrykas. When someone puts an item inside the chest, they receive something in return. Some gifts are treasures, some gifts are worthless and some gifts are dangerous.
I’ll also see if I can comb through the forum itself and scrounge up any of the official calendars. Thanks so much for doing this, Prophet!
