The trio of Rokelsh, Friadoc, and Jonas move into the room and immediately begin dispatching the pitiful creatures while the others wait to provide backup if needed.
Rokelsh easily drops two of them in succession, while Friadoc and Jonas take down one each.
The kobolds, what's left of them, flail about at random, and the trio easily avoid their weakened blows.
As the others look on they can see that several of the kobolds are degrading further even as they watch. Their little bodies seem to melt and regrow, expand and contract, and take on what appears to be additional features such as eyes and noses, before disappearing again.
As she looks at the bewildering sight, Tanith notices one in particular, and drops her jaw in horror.

After seeing one kobold in particular change, Tanith recalls a memory of some obscure tomb she's read, and recognizes the condition, and the new creature it has become. Suddenly the bolted door makes sense, and the tragic repercussions for their passing it are starting to sink in.
