And here comes our first ( temporary/wip ) visual for one of the characters you'll meet in TG.
This guy is an Eluwan.
Eluwans are a peacefull very smart type of aliens. You will usually find them working in the scientist and exploration branch. They make good navigators too. Some say that they have a spiritual side and that their motivations to help find the Tannhauser Gates may not be driven by pure scientist curiosity only.
