Title? I don't need no stinkin' title.
No plan ever survives first contact with the players.Well the joke's on me. They used Leomund's Tiny Hut instead - my god that thing is overpowered!
I did have a flock of Roc's hassle them on the carpet as the storm approached (they were trying to get the Hut ritual done before the Roc's attacked, unfortunately for them one of the Roc's managed to snatch one of the party before the ritual was completed, throwing that plan into disarray). Thrills and spills ensued but they managed to deter the Rocs and get back on the carpet before the storm struck so they rode it out in the Hut. The storm however uncovered an ancient buried Ziggurat that just had to be explored (their choice of course - but this group loves exploration). They went in the next morning and began exploring, and then the cleric decided to break out Etherealness, but this time I was prepared and a creepy voice entered their minds as they transitioned to the Ethereal plane. We ended the session at that point with the players quite excited about what's going to happen next.
