Ok since AK151 did one of these about the Drakkar, then I shall do one about the sizzlings.
-The sizzlings started out as a group of humans who crashed on the planet Sizzle 130 years ago. Since the humans were stranded, they abandoned their crashed ship and explored out to the mountains which were made of crystals. They then started to harvest the crystals with their cutting tools and technology from their ships. Over time those humans evolved into humanoids that have adapted to the harsh conditions on sizzle
-The sizzlings have a society that is based on monarchy where a king and queen rule the planet. However on sizzle everyone is treated equal except for the royal family which they are royal meaning they are treated a bit higher than everyone else.
-They are on average 2 meters tall and are kinda fat so they don't starve in the harsh winter. They are in a way like plump kaminoians but are more human. Usually they are kind srong people.
- Sizzling tech is up to date mostly thanks to the styguim crystals found naturally on the planet. They make sizzle guns, cannons, and sizzle bolter. The sizzle bolter is that super weapon thing on the sizzle cruisers though acts like that special weapon equipped on agressor destroyers used by Tyber Zahn.
Well that is about it
