The coyns Stofsk , used in the casting ritual designate what caste a chirper-soon-to-be-Droyne will fulfill in its oytrip.
Everyone else above are of course correct, the best suited player character type caste of the Droyne is the Sport caste.
alien RP-ing opportunities abound with Droyne, simply from thir viewpoint, not just physiologically.
Droyne pratice a form of euthanasia, for example. When your time comes as a Droyne, you are expected to undertake ritual suicide--your purpose and worth to the oytrip is fulfilled, you have been replaced and Krinaytsyu (ritual death) is undertaken.
Droyne who seek to avoid this fate, and run are pursued into far exile with the title of Krinaytsyoyni, the 'deathless ones', who deny the ritual.
Other alien RP oddities & opportunities:
Droyne are divided into six castes, and while not like the K'kree who do things by the herd, normally do things done at the dreskay (Family unit of 5-6 individuals). a "collection of these" make up an Oytrip, according to Traveller's Alien Module: Droyne..
The other small group, is also measured in the same numbers, the Kroyloss or "fraternity"
Droyne handbuild their starships (those that have starflight), so while there are similiar inside features, each one exterior wise will differ as well. Those who move off and explore, or conduct trade form Iyuksimin (or 'tendrils', literally) from their parent group.
The Droyne casting ritual is a Psionic one, led by the Aykrusk The leader (Psionic Priest) caste. Droyne psionics are different from human known ones. The Droyne leadership caste in large communities (Oytrips again) have thier own Psionic council, and choose among their number their leader of leaders, or Aykrusk’unkrus.
I admit there isn't a plethora of data in what we do have from various flavors of Traveller Stofsk, but from the basics above, and some of what I have shared one could:
a) Have Sport caste who is looking for a deathless one, who has hidden among humans and must bring him/her/it back to face the death ritual, or carry out the sentence.
b) Have a sport sent to find out the fate of a missing 'tendril's' ship and its crew which is overdue.
c) Have Sport act as an emissary for a powerful Oytrip on a world seeking trade, economic parity, or diplomatic relations with a Psion led human or other world. On a flip side, this emissary/ courier could also be delivering word of Oytritsyu'a, the total war between communities.
d) Act as a Spy on human worlds nearby for the Oytrip for the purposes of choosing with whom to trade, not trade, etc with..
and so on. Hope this helps stofsk.
