Each city and commune has a small quest that will award a special Solstice gift upon completion. These quests can be done by anyone from newbie to demigod. Note that you can only gain your own commune or city's gift! Find the denizen in question and greet them for more details. You can find them at the temporary landmarks available for each nation.

In New Celest, Eraol Flenn seeks stars in a jar. (celestsolstice)
In Magnagora, Jinlu Ilithya seeks rats in hats. (magnasolstice)
In Serenwilde, Caedir Aormeah seeks does in the snow. (serensolstice)
In Glomdoring, Dominique Nightshade seeks beasts of the feast. (glomsolstice)
In Hallifax, Ki'kia zi'Prouep seeks beryls in peril. (hallisolstice)
In Gaudiguch, Mosachi Xeeth seeks lizards with gizzards. (gaudisolstice)

This year's reward is a snowglobe that shows how your organisation celebrates Solstice and allows you to cast a decorative enchantment on yourself or someone else! This effect adds a line to your description that matches your organisation's themes and which can be reapplied at will. It will last for 3 hours or until you SCRUB it with water or soap.

Additionally, each city and commune's dedicated store selling the rewards of previous Solstice adventures is once more open. Anyone who has missed out on getting them in the past will be able to make up for it each Solstice season. Be sure to read the display in the shop describing what each item does - these take the form of signs, fountains, bark, or even imps. As aethergoop will be phased out, all the items are now also available in credits. The shops can be found:

In New Celest, by the lobby of the Syrinx Plaza Hotel.
In Magnagora, within the construction site south off Sombre Lane.
In Serenwilde, southwards from the Ellindel Memorial.
In Glomdoring, a hollow by the Stables of the Wyrden Thorn.
In Hallifax, up the stairs from the Ministry of Commerce and Exchange.
In Gaudiguch, within one of the rooms of the Dapper Dashro Lounge.
