'House of the Dragon' Season 2, episode 4: Who is Alyn, and why might he be important?

A new season of House of the Dragon usually means a few new faces — and while none of the new characters in Season 2 have had huge roles to play yet, there are a couple who certainly fall into the "ones to watch" category.

One of the new guys getting a fair bit of screen time? Alyn (Abubaker Salim), a sailor working on Lord Corlys' (Steve Toussaint's) Velaryon fleet. But who exactly is he, and why might he be important?
