I've got a few questions about Theno:

1) We know Theno have fin-like protrusions near their ears and have smooth skin.

But for absolute clarity's sake, is it possible for Theno to have other features such as:

1a) Fish-like scales on parts of their body.
1b) Gills.
1c) Fins in other locations. (E.g. On top of their head, back, arms or legs?)
1d) Fish-like tails.
1e) Irregular skin colour. (E.g. Blue skin)


2) Are Theno able to breathe underwater or can they hold their breath for extended periods? Assuming one or the other, how long can they generally do this for?


3) We know Theno are native to the seas south of Egwyn and tend to live on small islands. Are there a series of islands south of Egwyn then? If so, do they have a known name?


4) I'm curious about some of the general culture around Egwyn-based Theno:

4a) For instance, what's their social structure like? Do they live in tribes like other Egwyn natives? Do they have roles such as a chieftain, shamans, warriors, hunters, gatherers and so on?

4b) If they're tribal, is there one big tribe or a handful of smaller tribes south of Egwyn?

4c) How do these Theno typically treat others? Such as foreigners or even other Egwynians?

4d) Are there any notable laws or rules to these Theno?


5) What's the average lifespan for a Theno?
