Living among the Bat-folk, Chapter 5 – Festivities, Rituals and Customs. Page 334
Considering how important is social relationships for the Kalang, it is not a big surprise they usually hold events all year-round, commemorating many phases in their lives, and other such things of importance. Even visitors are expected to join the celebrations, and the slight refusal is apparently greatly frowned upon.
A new year in a Ka’s society starts as soon as they rise from Hibernation, in the beginning of spring. They hold a feast, which they aptly name “The First of Many Feasts”. They don't usually wear anything especial for this feast, in case some elfic fashion afficionado is interested to know.
It’s a surprise to learn that it lacks the idea us Dwarves have for feasts, as in fact they eat very little; mostly it’s plain water, a bug soup they call “Melolontha”, and fruit cakes they prepared before hibernation. Don’t expect roasts or beer, friends! The Kalang say eating such things after long periods of not eating give them cramps. And a cramped Ka won’t be able to dance.
