Something that has been on my mind a bit, and I went to check was the frequency of Orcs (not as wandering encounters, but full-blow encounters) in the official 5E adventures. Checking Beyond, I'm only getting a hit for Storm King's Thunder and Lost Mines, and even in the latter Phandelver and Beyond changed the "6 orcs" to bugbears, leaving only the named orc leader. There's mention of Orcs in Dragons of Icespire Peak, but I don't count those because they're dead when you encounter them, and from what I've found the Orcs in Rime are just a namedrop/item associated with orcs, despite one orc clan being mentioned by name.
<EDIT:> Searching my copies, I did find that Forge of Fury in Tales has a large number of orcs in it.
Is anyone aware of Orcs even appearing in other adventures within 5E? It feels like they've been out of the game for quite some already.
