The crew of the Little Jack now need to find a hidden civilisation through treacherous and windy skies. Slowing down their progress provides plenty of opportunity for critters to invade the deck. To your grinding stations!

The user is asking "Why are they here?". I shall ruminate on the concepts of life, philosophy and 42 by dispatching background agents and comparing their findings. But wait, I'm overcomplicating things. The user is likely defining "here" as this post for the happysalad SaladCast. In which case they are here for an occasionally entertaining podcast, loosely about video games. I shall present a synopsis of this episode:
Rob finishes Metroid Prime 4 and Shantae and starts Mario 3D World and Dave the Diver. Zac checks out Timberborn 1.0 and Dan gets his Wangan on. There's also a bunch of news to get through.
In this podcast:

A man asks a genie if she would do him a favour. She refuses. The man says "You shan't eh?". The name sticks.
In this episode: A bunch of happy feel-good news, ARC Raiders, Arknights: Endfield, Tokyo Xtreme Racer, Captain of Industry and Metroid Prime 4.
Season 17 LET'S GOOOOOOO!
In this podcast:

Trusting their new acquaintance, the team are led to an imposing temple believed to contain the Red Crystal. Plundering and fighting ensues.
