Edit: tldr - looking for a published adventure, probably a one shot, involving a temple with catacombs or a dungeon l underneath it. For low level preferably

Full version: So, I haven't played D&D since the pandemic hit, and I'm probably running a game next week. I'm a little rusty and I haven't had enough time to prep.

I'm looking for an adventure that I could buy and either use it as is or repurpose based on the plot and setting.

The game takes place in greyhawk and the characters are going into orcish-occupied Eastern Ulek to retrieve an item from a temple that was abandoned or overrun when the orcs invaded.

My basic concept is that it's a temple of one of the good gods, and they built it in order to guard an evil maguffin that was found in the catacombs below where they built the temple. Now that the area has been overrun, the church thinks it's too risky to leave the artifact there and wants the PCs to retrieve it

I realize that's probably mostly unnecessary backstory, because I suppose what I'm really looking for is either a dungeon that could replicate a ruined temple and secret catacombs beneath it, or something that covers an outdoor area where the characters would be somewhat stealthily traveling to the temple

PCs will be level 3
