Obscure chapter: Jade Scorpions

A White Scars successors, of unknown founding and without any know heraldry, colour or chapter symbol

We know that their homeworld is Taongar, near the Veiled Regions

The only famous Jade Scorpion is Akrep Xie, Watchmaster of the watchfortress Eye of Octos in the Segmentus Ultima; other than this, we know basically nothing about this chapter

I imagine them as a more “chinese inspired” White Scars, so a little more focus on fire support and infantry than their progenitors, but always focused on fast attack tactics and an heavy use of bikes, transports, aircraft and jump packs; for the symbol, a scorpion could be the best bet, maybe in green, an usual color associated with jade in general

What do you think of them? Any ideas to embellish them?
