[@Vertigo] Hmm... I forgot about Kenku. I might have to say no to that; I intend for this to be high/medium roleplay. Not every conversation needs to end in a quest - and not every battle will end by killing or subduing all of the enemies. Their lack of voice might make this difficult for you. I want to stay true to the lore, but if you are dead set on the Kenku, then we can discuss it, or come up with an alternative (such as a raven-themed aarakocra with some kenku traits).[/quote]

Hmm, I might have misunderstood their lore, then; I took this 

[quote]can communicate only by using sounds they have heard. Most kenku use a combination of overheard phrases and sound effects to convey their ideas and thoughts. [/quote] 
to mean that as long as they have heard someone use certain words and phrases, they'd be able to use them in turn - it'd just be sort of a patchwork job and they wouldn't be really eloquent. Kind of like someone speaking a foreign language they're still learning; not able to use idioms or imaginative descriptions, but able to communicate on an understandable level by using what they know and substituting more complicated words for simpler ones.

EDIT: A [url=https://twitter.com/JeremyECrawford/status/956670426934947841]tweet [/url] from Jeremy Crawford seems to suggest something similar.

Another one [url=https://twitter.com/JeremyECrawford/status/956687735208656896]here[/url], as well.

Could I PM my idea to you to see if it'd fly? (Pun unintended but fitting). If it seems like it'll be a no go in the end, that's also fine; I do have an old idea for an Aarakocra that I've yet to get to use, so it can be my backup. So I'm not dead set and can change if needed!
